Mathematical Sciences
Mathematics is one of the oldest disciplines of study. For all its antiquity, however, it is a modern, rapidly growing field. Only 70 years ago, mathematics might have been said to consist of algebra, analysis, number theory and geometry. Today, so many new areas have sprouted that the term “mathematics” seems almost inadequate. A new phrase, “the mathematical sciences” has come into fashion to describe a broad discipline that includes the blossoming fields of statistics, operations research, biomathematics and information science, as well as the traditional branches of pure and applied mathematics.

Mathematics Major
Requirements
The mathematics major has a foundation requirement, a core requirement, a depth requirement and a total credit requirement.
 Foundation: MTH 111, MTH 112, MTH 153, MTH 211 and MTH 212
 Core
 One course in algebra: MTH 233 or MTH 238
 One course in analysis MTH 280 or MTH 281
 Depth: One advanced course, (a MTH course with a course number between 310 and 390)
 Electives to reach 36 credits at or above MTH 153
 With the approval of the department, up to 8 of the credits may be satisfied by courses taken outside the department of Mathematical Sciences. Courses taken outside the department must contain either substantial mathematical content at a level more advanced than MTH 211 and MTH 212 or statistical content at a level more advanced than SDS 220. Generally, such a 4credit course will be given 2 credits toward the mathematics major.
 Crosslisted courses (see the Courses tab) are counted as mathematics courses and given full credit toward the mathematics major, as does ECO 220.
 The following courses meet the criteria for 2 credits toward mathematics major: AST 337, CHM 331, CHM 332, CSC 240, CSC 252, CSC 274, a topic in CSC 334 , ECO 240, ECO 255, EGR 220, EGR 315, EGR 320, EGR 326, EGR 374, EGR 389, PHI 102, PHY 210, PHY 317, PHY 318, PHY 319, PHY 327, and SDS 293. A student may petition the department if they wish credit for any course not on this list.
Mathematical Statistics Major
The major in mathematical statistics (MST) is designed to prepare students for graduate study in statistics and closelyrelated disciplines (e.g., biostatistics). The mathematical statistics major overlaps with the major in statistical & data sciences (SDS), but places a heavier emphasis on the theoretical development of statistics. Mathematical statistics majors will develop sophisticated mathematical skills to prepare for rigorous future study. The major also overlaps with the major in mathematical sciences (MTH), but focuses on statistics and replaces the algebra requirement with a computing requirement.
A student majoring in MST cannot have a second major in either SDS or MTH. Students contemplating a double major in MTH and SDS should choose to major in MST.
Requirements
Ten courses
 Mathematical foundations (3 courses): MTH 153, MTH 211 and MTH 212
 Statistical foundations (2 courses)
 SDS 201 or SDS 220
 SDS 291
 Statistics depth (1 course): SDS 290, SDS 293 or a topic in SDS 390
 Mathematics depth (1 course): MTH 280 or MTH 281
 Programming (1 course): SDS 192, CSC 110 or CSC 120
 Theoretical statistics (2 courses): MTH 246 and MTH 320/ SDS 320
 Electives to complete ten courses. Five College course in statistics, mathematics and computer science may be taken as electives. Students should consult with their adviser to determine appropriate electives.
Major Requirement Details
 SDS 220 or SDS 201 may be replaced by a 4 or 5 on the AP statistics exam. Replacement by AP scores does not diminish the total of 10 courses required for the major (see Electives above).
 A student may replace MTH 153, MTH 211 and MTH 212 with equivalent courses as approved by the MTH department.
 Any one of ECO 220, GOV 203, PSY 201 or SOC 204 may directly substitute for SDS 220 or SDS 201 without the need to take another course. Note that SDS 220 and ECO 220 require Calculus.
 Normally, all courses that are counted towards either the major or minor must be taken for a letter grade.
Honors
A student majoring in mathematics may apply for the departmental honors program. An honors project consists of directed reading, investigation and a thesis. This is an opportunity to engage in scholarship at a high level. A student at any level considering an honors project is encouraged to consult with the director of honors and any member of the department to obtain advice and further information.
Normally, a student who applies to do honors work must have an overall 3.0 GPA for courses through their junior year, and a 3.3 GPA for courses in their major. A student may apply either in the second semester of their junior year or by the second week of the first semester of their senior year; the former is strongly recommended.
Requirements
 Credits required for the major
 MTH 430D or MTH 432D (for either eight or twelve credits) or (in unusual circumstances) MTH 431. The length of the thesis depends upon the topic and the nature of the investigation and is determined by the student, their adviser and the department.
 An oral presentation of the thesis
The department recommends the designation of Highest Honors, High Honors, Honors, Pass or Fail based on the following three criteria at the given percentages:
60 percent thesis
20 percent oral presentation
20 percent grades in the major
Specific guidelines and deadlines for completion of the various stages of an honors project are set by the department as well as by the college. The student should obtain the department’s requirements and deadlines from the director of honors.

Applied Statistics Minor
Information on the interdepartmental minor in applied statistics can be found on the Statistical and Data Sciences page of this catalog.
Course Information
A student with three or four years of high school mathematics (the final year may be called precalculus, trigonometry, functions, or analysis), but no calculus, normally enrolls in MTH 111. A student with a year of AB calculus, A levels or IB math SL normally enrolls in MTH 153 and/or MTH 112 during the first year. Placement in MTH 112 is determined not only by the amount of previous calculus but also by the strength of the student’s preparation. If a student has a year of BC calculus or IB math HL, they may omit MTH 112.
A student with two years of high school mathematics, but no calculus or precalculus, should enroll in MTH 102.
Topics offered in MTH 105 are intended for students not expecting to major in mathematics or the sciences.
A student who receives credit for taking MTH 111 may not have AP calculus credits applied toward their degree. A student with 8 AP Calculus credits (available to students with a 4 or 5 on the AP exam for BC Calculus) may apply only 4 of them if they also receive credit for MTH 112. A student who has a score of 4 or 5 on the AP Statistics examination may receive 4 credits. They may not however, use them toward their degree requirements if they also receive credit for SDS 201, SDS 220, PSY 201 or ECO 220. (AP credits can be used to meet degree requirements only under circumstances specified by the college.)

If you'd like to declare a math major or minor, the first step is to fill out an advisor preference form here.
Postbaccalaureate Program
Sponsored by the Center for Women in Mathematics, the Postbaccalaureate Program is for women with bachelor's degrees who did not major in mathematics or whose mathematics major was light. This program is open to all women who have graduated college with some course work in mathematics above the level of calculus, and a serious interest in further pursuing mathematics. More information about the program is provided by the Center for Women in Mathematics.
Masters of Arts in Teaching
The Department of Mathematical Sciences cooperates with the Department of Education and Child Study to offer a one–year Master of Arts in Teaching (MAT) program.
During one summer and two semesters, MAT candidates take three courses in mathematics and all the course work required for secondary teacher certification in Massachusetts. The program includes a semester–long internship in a local school. Applicants for the MAT program in mathematics should have an undergraduate degree in mathematics. College graduates with a different major will be considered if their undergraduate education included a strong foundation in mathematics.
FifthYear Master of Science in Statistics
Qualified graduates of the Department of Mathematical Sciences can apply to the University of Massachusetts Amherst to earn a master's degree in statistics in a fifth year. Learn more about the program.
An honors project consists of directed reading, investigation and a thesis. This is an opportunity to engage in scholarship at a high level. A student at any level considering an honors project is encouraged to consult with the director of honors and any member of the department to obtain advice and further information.
Honors projects in the Department of Mathematical Sciences are worth 8–12 credits. Ideally, your program should be approved by the department in the spring before your senior year. (You might also consider applying for a summer research grant from Smith so you can spend the summer before your senior year in Northampton beginning the work on your project.)
Eligibility
Normally, a student who applies to do honors work must have an overall 3.0 GPA for courses through her junior year, and a 3.3 GPA for courses in her major. A student may apply either in the second semester of her junior year or by the second week of the first semester of her senior year; we strongly recommend the former.
Financial Assistance
The Tomlinson Memorial fund provides financial assistance for honors thesis projects. If you're interested in obtaining funds you must complete the application form "Financial Assistance for Departmental Honors" and submit it with your honors application. This application form can be obtained from the director of honors or the class deans office.
Timeline*
Typically, you meet with your project adviser several times a week. Usually the project focuses on one area and involves reading mathematics papers and books at an advanced level. The honors paper you write will be an assimilation and exposition of the area. Occasionally, a project will include new contributions by the student. By early spring, most of your research should be complete and you will begin writing. The paper is due in the middle of April. It is read by a panel of faculty members, and in early May you present a talk to the department on your work.
Presentation of Thesis
Smith College rules stipulate that the final draft of your thesis must be submitted to your faculty adviser (first reader) and second reader by April 15*. This final draft will be the one subject to evaluation by the first and second readers. Honors candidates give a 45minute oral presentation of their honors research for the mathematics faculty, which will be open to all interested members of the Smith College community and others by invitation.
You should expect to take questions from the audience during and after the presentation. Following the open presentation there will be an additional question period for the mathematics faculty only. This presentation will be scheduled during the last week of classes, or reading period, but no later than the last day of the preexamination study period.
Evaluation
 60% thesis
 20% oral presentation
 20% grades in the major
Your grade for the project (pass, distinction, high distinction, highest distinction) is determined by a combination of your grades on the paper, the presentation and your mathematics courses. The presentation has the least weight in your grade, but it gives us all a chance to hear about what you have done. We also invite you to give a talk to your fellow majors, though this is not part of the official process.
*Timeline is for May graduates. Consult your adviser about dates if you plan to graduate in January.
The Math department does not have a designated placement test for math and statistics courses. Descriptions of common starting courses, advice on how to decide between them and information about AP and IB credit is available on the Introductory Mathematics Courses website and on the document below.
Additional Course Information
Whatever your reasons to study math or statistics, we, or our colleagues in Statistics & Data Science, have something for you! And by the time you take a course with us, we hope that you will have enjoyed it so much that you will take another one just because it’s cool…
Why do I need math at all?
If you haven’t enjoyed your mathematics courses or have found them frustrating, the need to take more math in college for your major can be irritating. Or maybe you are delighted that you’ll be taking more math! Students have completely different experiences of mathematics courses, and here we would like to lay out some reasons that all students should be excited about taking math.
You have probably heard the refrain “Math is everywhere!” many times before, and it’s true: math IS everywhere. From computing your GPA (a weighted average) to understanding how debt works (compounding interest), math runs through most facets of our lives, and increasingly in the data driven industry. For instance, how should a large trucking company allocate its storage of empty trailor around the country to minimize the number of miles empty trailors travel? This is a difficult math problem that generates jobs and saves the environment!
In practical terms, even if you do not choose to do a math major, a number of other majors  and professions!  require math. The most common ones are:

MTH 111 Calculus I (Economics, Engineering, Physics, Statistics & Data Science, Prehealth)

MTH 112 Calculus II (Engineering, Physics)

MTH 153 Discrete Math (Computer Science)

MTH 211 Linear Algebra (Statistics & Data Science)

MTH 212 Calc III (Engineering, Physics)

SDS/MTH 220 Intro to Probability and Stats (Statistics & Data Science, Biology, Economics; recommended for Engineering and Prehealth)
What courses am I prepared to take?
A student who wishes to study mathematics may place herself according to the following guidelines.

Any student who is curious about mathematics outside of the standard fields seen in high school may consider Discovering Mathematics (MTH105). Some incarnation of the course have explored arts and math, the role of chance in our lives, and measuring social inequalities.

A student with three years of high school math (typically one year of geometry and two years of algebra) is ready for Elementary Functions (MTH102), which can prepare them to take Calculus I.

A student with four years of high school math (but little or no calculus) can take Calculus I (MTH111).

A student with a year of high school calculus is ready to take Discrete Mathematics (MTH153) or Calculus II (MTH112).

Wellprepared students might start at Smith with Linear Algebra (MTH211) or Calculus III (MTH212).
Below is a more detailed document matching your preparation with possible courses.
Mathematics, Statistics, and You
For statistics courses you are prepared to take, consult this Statistics and Data Science page.
For detailed information about the introductory calculus courses as Smith, including how they work and they help you do the things you want to do with your time at Smith, visit the Introductory Mathematics Courses at Smith website.
The introductory calculus courses (MTH111: Calculus 1 and MTH112: Calculus 2) at Smith are offered in small sections of 2028 students, taught by different professors. The sections of each introductory course are closely coordinated to maximize the resources available to students and make it easy for students to work together during the semester. Those resources include department peer tutors, quantitative skills tutors through the Spinelli Center for Quantitative Learning, and the department Calculus Training Group program, profiled in Grecourt Gate in November 2017.
For those who either do not intend to take Calculus or who have already taken enough of it, there is math besides Calculus!
MTH153: Introduction to Discrete Mathematics
Description: An introduction to discrete (finite) mathematics with emphasis on the study of algorithms and on applications to mathematical modeling and computer science. Topics include sets, logic, graph theory, induction, recursion, counting and combinatorics.
Offered: Every semester
Prerequisite: None, but MTH111 and familiarity with summation notation is recommended
Great for: Computer Science, Mathematics & Statistics, Statistics & Data Science – the study of logic and algorithms is necessary for good coding. In addition, you learn a variety of proof techniques, which are key for going deeper in mathematics as a whole.
MTH211: Linear Algebra
Description: Systems of linear equations, matrices, linear transformations, vector spaces. Applications to be selected from differential equations, foundations of physics, geometry and other topics.
Prerequisite: MTH 112 or the equivalent, or MTH 111 and MTH 153; MTH 153 is suggested
Offered: Every semester
Great for: Almost everyone, but specifically Computer Science, Mathematics & Statistics, Statistics & Data Science, Economics. Linear algebra is the workhorse subject of modern mathematics. Any work with data relies on an understanding of matrices. Linear algebra is even used to help identify exoplanets in astronomy! It turns up pretty much everywhere.
Required for: MTH and SDS majors.
MTH212: Calculus III
Description: Theory and applications of limits, derivatives and integrals of functions of one, two and three variables. Curves in two and three dimensional space, vector functions, double and triple integrals, polar, cylindrical, spherical coordinates. Path integration and Green’s Theorem.
Prerequisites: MTH 112. It is suggested that MTH 211 be taken before or concurrently with MTH 212.
Offered: Every semester
Great for: Physics, Engineering, Mathematics & Statistics, Economics. Calculus III takes everything from calculus and moves into multiple dimensions. For physics and engineering, understanding of more than one dimension is essential for modeling how objects move through our multidimensional space. In economics, you often need to optimize quantities with many different inputs (and sometimes outputs!) which Calculus III can do.
Required for: EGR and MTH majors.
MTH/SDS220: Introduction to Probability and Statistics
Description: An applicationoriented introduction to modern statistical inference: study design, descriptive statistics; random variables; probability and sampling distributions; point and interval estimates; hypothesis tests, resampling procedures and multiple regression. A wide variety of applications from the natural and social sciences are used. Classes meet for lecture/discussion and for a required laboratory that emphasizes analysis of real data.
Prerequisite: MTH 111 or the equivalent, or permission of the instructor. Lab sections limited to 20
Offered: Every semester
Great for: Everybody. Data analysis is a growing field and understanding how to work with data is useful in many fields. MTH 220 satisfies the basis requirement for biological science, engineering, environmental science, neuroscience and psychology.
Required for: BIO, EGR, ESP, NSC, PSY, SDS.
Note: Other departments offer statistics courses with different prerequisites, and for which SDS 220 may be substituted (e.g. PSY/SDS 201, ECO 220)
Consult the Smith College Course Catalog for information on the current courses available in mathematics and statistics.
There are also several courses that are available for credit from other departments, including art, psychology and more. Consult the catalog.
What classes you should take depends a great deal on what you find most interesting and on what your goals are. Discuss your options with your adviser and also talk to the instructors of particular courses that interest you.
If you are interested in the sciences:
The department offers a variety of courses to give you a solid mathematical experience. Calculus III and Linear Algebra are fundamental courses. You may also want to consider taking one or more of the following: Intro to Probability and Statistics, Differential Equations, Differential Equations and Numerical Methods, Discrete Mathematics, Advanced Topics in Continuous Applied Mathematics.
If you are interested in computer science:
Consider taking some of these: Calculus III, Linear Algebra, Modern Algebra, Discrete Mathematics. Many of our students are double–majoring in mathematics and computer science.
If you are interested in economics:
Calculus will give you a good, basic experience. You may consider other courses as well, so be sure to discuss your options with your adviser. If you are contemplating graduate school in economics, the economics department recommends you to take MTH 211, 212, 280 and 281. Taking a solid course in statistics is also a good idea (any of MTH 220, 246, 290, 291 and 320 would do). Many economics majors want to take MTH 264 as well. Double–majoring in mathematics and economics is a good choice.
If you are interested in applied mathematics:
The following courses work specifically with applications: MTH 205, 264, 353 and 364. Other courses that contain many applications and are important for anyone considering graduate school in applied mathematics are: MTH 220, 246, 254, 255, 280, 290, 291, and 320.
If you are interested in theoretical mathematics:
The following courses work with abstract structures: MTH 233, 238, 246, 254, 255, 280, 281, 333, 370, 381, and 382.
If you liked calculus:
There are many reasons for liking calculus. If you delighted in the geometry, for example, you should consider MTH 270, 280, 370 and 382. If you enjoyed the power of calculus to describe and understand the world, you will want to take MTH 264. If you are fascinated with the ideas of limit and infinity and want to get to the bottom of them, you should take MTH 281.
If you liked linear algebra:
You will like MTH 233 very much, and you will also like MTH 238 and 333.
If you liked discrete mathematics:
The natural sequel to Discrete Mathematics is MTH 254 or 255 and then 353. In addition, you may be interested in MTH 246 and in CSC 252 (counts 2 credits toward the mathematics major).
If you are interested in graduate school in mathematics:
Take a lot of courses, but be sure to take MTH 233, 254, and 281 and as many of MTH 264, 333, 370, 381, and 382 as possible. You should also consider taking a graduate course at the University of Massachusetts.
If you are interested in graduate school in statistics:
The MST Mathematical Statistics joint Major between MTH and SDS is explicitly designed as a preparation for graduate school in Statistics.
If you are interested in graduate school in operations research:
Operations research is a relatively new subarea of mathematics, bringing together mathematical ideas and techniques that are applied to large organizations such as businesses, computers, and governments. You should take MTH 211 and at least some of the courses listed for statistics above, some combinatorics (MTH 254) and some computer science. Consider also Topics in Applied Mathematics and Numerical Analysis.
If you want to be a teacher:
Certification requirements vary widely from state–to–state. If you are interested in teaching in secondary school, a mathematics major plus practice teaching may be enough to get started. In Massachusetts, the major should include either MTH 233 or 238 and one of MTH 220 or 246. A course involving geometry, such as MTH 270 or MTH 370 is also helpful. You should also have some introduction to computers. For guidelines, look at the list of courses listed in the MAT program. Finally, while MTH 307 Topics in Mathematics Education is rarely offered, something equivalent is taught as a special studies whenever there are MAT students.
If you are interested in teaching elementary school, most of your required courses will be in the education department. In the mathematics department, our concern would be that you are comfortable with mathematics, have seen its variety, and most important, that you enjoy it. For all that, you should take the mathematics courses which appeal to you most. For education courses, the latest information is that you should take EDC 235, 238, 346, 347, 404 (practice teaching), and one elective to be certified. Note that during the semester when you take practice teaching EDC 404, you will likely be unable to take a math course. Plan ahead and consult the education department.
If you want to be a doctor:
You are doing fine by majoring in mathematics. A course in statistics would be a very good idea. Other areas of mathematics that would be useful are differential equations and combinatorics.
If you want to be an actuary:
Take MTH 246, 290, 291 and 320 and the actuarial exams that are offered periodically. Advancement as an actuary is achieved by passing of a series of examinations. Informal student study groups often form (ask around!).
If you want to get a good job when you graduate:
A major in mathematics prepares you well, regardless of which courses you choose. Math majors learn to think on their feet; they aren't frightened of numbers and they're at home with abstract ideas. Often, this alone is what employers are looking for. That said, we should add that knowledge of computer programming is very useful, as is some familiarity with statistics.
If you want something Smith does not offer:
If you are interested in a subject we do not offer, you should talk to professors whose fields of interest are closest to the subject, as a special studies. The arrangement must be approved by the department, but reasonable requests are not refused. If your interest is particularly strong, you might consider an honors project, or summer research work. You should also consider taking a course (or courses) at one of the consortium schools.
