Unit 3 Summary

Math for CS · Axiom Academy

Everything you learned, in one concise review Inclusion-Exclusion: |A B| = |A| + |B| - |A B| Cartesian Product: |A B| = |A| |B| Difference: |A B| = |A| - |A B| With set theory mastered, you are ready for: Functions — mappings between sets ( f: A B ) Relations — subsets of A B with special properties Combinatorics — counting techniques built on set operations Propositional Logic — the parallel universe where sets become propositions
