Introduces the fundamental language, logic, and proof techniques essential for advanced mathematics. Emphasizes how to read, understand, and construct rigorous mathematical arguments. Topics include propositional and predicate logic, set theory, proof by contradiction, induction, and the axiomatic method. Designed for students transitioning from computational to proof-based mathematics.

For many students entering the hallowed halls of the Massachusetts Institute of Technology, there is a silent, often terrifying, academic barrier. It is not calculus—most MIT freshmen have already mastered differentiation and integration in high school. It is not linear algebra or differential equations. The true hurdle is mathematical maturity.
In this course, words have extremely precise meanings. You cannot prove a function is "continuous" if you cannot write down the exact epsilon-delta definition.
