**MATH-100 Precalculus**

**MATH-100QR Precalculus: 'Problem Solving and Quantitative Reasoning'**

*Fall. **Credits: 4*

This course is intended for students who, based on the results of their mathematics assessment and the agreement of the instructor, need to strengthen their quantitative and algebraic skills in order to be ready to progress to further mathematics, science, and economics courses. In this class students learn to translate real problems into mathematics, to solve complex multi-step problems, and to gain confidence in using logarithms, exponents, and trigonometry in different contexts.

**MATH-114 Explorations in Number Theory**

*Not Scheduled for This Year. **Credits: 4*

We will cover the arithmetic of whole numbers and of prime numbers, in particular, examining some of the earliest questions in mathematics from a modern perspective, finding whole number solutions to equations with several variables, deciding whether or not such solutions exist and if so, determining whether the solution set is finite or infinite. Topics include the theory of 'finite arithmetic,' converting questions about the infinite set of whole numbers to those involving just a small set of primes, using computers to examine problems numerically.

*Applies to requirement(s): Math Sciences**The department**Advisory: A good grasp of arithmetic*

**MATH-120 Explorations in Geometry**

**MATH-158MM Developing Mathematical Ideas: Making Meaning for Operations**

*Not Scheduled for This Year. **Credits: 2*

This course provides opportunities for participants to examine the actions and situations modeled by the four basic operations. The course will begin with a view of young children's counting strategies as they encounter word problems, moves to an examination of the four basic operations on whole numbers, and revisits the operations in the context of rational numbers.

**MATH-158ST Developing Mathematical Ideas: Building a System of Tens**

*Not Scheduled for This Year. **Credits: 2*

Participants will explore the base-ten structure of the number system, consider how that structure is exploited in multi-digit computational procedures, and examine how basic concepts of whole numbers reappear when working with decimals. They will study the various ways children naturally tend to think about separating and combining numbers and what children must understand in order to work with numbers in these ways.

**MATH-312 Abstract Algebra**

**MATH-312GT Abstract Algebra: 'Groups'**

*Not Scheduled for This Year. **Credits: 4*

Abstract algebra is the study of the common principles that govern computations with seemingly disparate objects. One way to begin is by studying groups, which are sets with a single operation under which each non-identity element is invertible. Examples include the integers with addition, invertible matrices of size n, permutations of a fixed set, and the symmetries of an object. Our goal is to study a definition of groups that unifies all of the important examples above and more.

**MATH-312RT Abstract Algebra: 'Rings'**

*Fall. **Credits: 4*

Abstract algebra is the study of the common principles that govern computations with seemingly disparate objects. One way to begin is by studying rings, which are sets with two operations, typically addition and multiplication. Examples include the integers, the integers modulo n, and polynomials in n variables. Our goal is to study a definition of rings that unifies all of the important examples above and more.

**MATH-319 Topics in Algebra**

**MATH-319CT Topics in Algebra: 'Combinatorics'**

*Fall. **Credits: 4*

This course is an investigation into the art of counting and combinatorial proof. Many mathematical formulas can be interpreted as counting some collection of objects with a particular structure. This allows us to apply simple counting arguments, and often we obtain beautiful and concrete proofs. Topics may include Fibonacci identities, Stirling numbers, inclusion-exclusion, continued fractions, and generating functions.

The laboratory provides a range of experiences that enhance and sharpen the theoretical approach and, moreover, allows us to observe regularities in complex phenomena and to conjecture theorems. Topics include: introductory experiments; axiomatic probability; random variables, expectation, and variance; discrete distributions; continuous distributions; stochastic processes; functions of random variables; estimation and hypothesis testing.
