Three class hours per week. Class sessions combine lecture with active problem-solving and peer discussion. Weekly problem sets emphasize writing complete, well-structured proofs.
Students must have completed 18.01 (Single Variable Calculus) . 18.090 introduction to mathematical reasoning mit
Unlike a lecture-heavy physics course, 18.090 is structured for active struggle. Course Overview
MIT does not currently have a full OCW (OpenCourseWare) version of 18.090 with video lectures, but the spirit of the course is reproducible. If you want to replicate the 18.090 experience at home, assemble the following toolkit: Format: Three class hours per week
: It provides a lower-pressure environment to "struggle and wrestle" with abstract concepts—skills that are essential for the more brutal problem sets in the Pure Math major. Key Topics You’ll Conquer
