Methods of proof (induction, contradiction), infinite sets, and logical quantifiers.

At institutions without a course like 18.090, the first "proofs" class is often Real Analysis (18.100) or Abstract Algebra (18.700). This is akin to teaching a foreign language by handing a student a Dostoevsky novel. The student is not only grappling with open sets, compactness, or group homomorphisms but is also simultaneously trying to learn the syntax of logical deduction. It prepares students for advanced courses such as 18

Naïve set theory (with a warning about Russell's paradox). Union, intersection, complement, power sets, and Cartesian products. You learn to prove two sets are equal by showing mutual inclusion: ( A \subseteq B ) and ( B \subseteq A ). : Sequences of real numbers and the formal

It teaches you how to think like a mathematician.

The syllabus of 18.090 is carefully curated to build a student's logical scaffolding from scratch. The course generally spans several fundamental pillars of discrete math and foundational logic. 1. Mathematical Logic and Propositional Calculus

Transitioning from geometric vectors to abstract spaces satisfying specific algebraic properties. 4. Introductory Concepts in Analysis
