### Mathematics Major (B.S.)

(see below for math minor requirements)

Eleven math courses are required to complete a major in mathematics, according to the following guidelines.

- These courses should include Math 135 and Math 136 (Calculus I and II), or their equivalent, for example in the form of AP credit. Students must also take Math 205 (Multivariable Calculus).
- Note that Math 110, 123 and 134 may not be counted toward the major. However, CS 140 (Introduction to Computer Programming) does count towards the major.
- Math majors are required to complete Math 280 (Bridge to Higher Math), either Math 305 or Math 306 (Real or Complex Analysis), and either Math 315 or Math 316 (Group Theory or Ring Theory).
- At least four of the eleven units must be at the 300 level or above. But note that the choices among Math 305, 306, 315, and 316 count as two of these four courses. A math SYE would count as a third such course; see below.
- All Statistics courses (with the STAT prefix) can be applied towards your math major at the corresponding level. For instance, STAT 113 will count as one of your eleven courses, and STAT 325 will count as one of your 300 level courses.
- All courses cross-listed with Mathematics count towards the major, such as CS 380, PHYS 333, or PHIL 302.
- Students are welcome to take further math courses, up to a maximum of fourteen units at St. Lawrence in total.

Students planning to major in mathematics are encouraged to complete Math 280 before the end of their sophomore year because this course is a prerequisite for many courses at the 300 level.

Students considering graduate work in mathematics are strongly encouraged to take Math 217 (Linear Algebra) along with all of Math 305, 306, 315, and 316 (a full year each of analysis and algebra).

*Important:* an SYE (Senior Year Experience) is required, either in mathematics as one of the eleven courses in the major or by completing an SYE outside the department. An SYE consists of an independent project, at the regular or honors level, conducted individually with a faculty member or as part of an SYE seminar with other seniors. All projects will include a written paper and a formal oral presentation. More information can be found on the SYE Info page. Please consult with the department chair to arrange a math SYE.

### Mathematics Minor

Seven math courses are required to complete a minor in mathematics. These courses should include Math 135 and 136, or their equivalent. (For example, in the form of AP credit.) Math minors must also take Math 205 along with four additional courses, three of which should be at the 200 level or above. Furthermore, CS 140 or STAT 113 can count towards the minor. Other 200 or 300 level Stats courses also count towards the minor, as do other cross-listed courses as described above. However, Math 110, 123 and 134 may not be counted toward the minor.

**Majoring/Minoring in both Mathematics and Statistics**

By their very nature, the disciplines of Mathematics and Statistics are closely connected, and several of the courses offered within our department can be used towards a major or minor in both. However, to ensure that students that wish to double major (or minor) in the two fields have sufficient depth of knowledge within each field, there are some limitations on the number of courses that can count to both.

Students planning to do this should devise a plan in writing with their advisor before getting approval for the second major.

Students planning to do this need to devise a plan in writing with their advisor before the department chair will approve the minor. This implies the Stat major will require an additional 7.5 units (beyond the Math core) and the Math minor an additional 3 (non-Statistics) units for a total of 14.5 units to complete the major and minor.
