Equivalence relations and partitions, which are the building blocks of abstract algebra.

MIT’s PRIMES (Program for Research in Mathematics, Engineering, and Science) has a public archive of "proof readiness" problems. These are short, elegant, and brutal. Equivalence relations and partitions, which are the building

This involves using logic to analyze problems and to formulate and evaluate mathematical arguments. This involves using logic to analyze problems and

Course description A rigorous introduction to mathematical reasoning: formal logic, proof techniques (direct, contrapositive, contradiction, induction), set theory, functions, relations, cardinality, equivalence relations and partitions, integers and divisibility, basic number theory proof exercises, sequences, limits (intuitive footing), counting and combinatorics, basic graph theory and algorithms, and introduction to real analysis style proofs. Emphasis on reading, writing, and critiquing proofs. Frequent problem sets and written proofs. Frequent problem sets and written proofs

, the class proved that the "infinity" of decimals is fundamentally larger than the "infinity" of counting numbers. Leo left the room feeling like he was walking on air. The world looked the same, but the foundation beneath it—the logic holding it all together—was suddenly visible, layered and deep. The Gateway to Greatness

It is specifically recommended for students who want more experience with proofs before tackling advanced subjects like 18.100 Real Analysis , 18.701 Algebra I , or 18.901 Introduction to Topology .
