What is Discrete Math?
Discrete mathematics deals with countable, distinct objects rather than continuous quantities. It includes set theory, combinatorics, graph theory, logic, and number theory.
Set Operations
- Union (∪): All elements in either set A or set B
- Intersection (∩): Elements common to both sets
- Difference (−): Elements in A but not in B
- Symmetric Difference (△): Elements in A or B but not both
Combinatorics Formulas
- Combinations: C(n,r) = n! / (r!(n-r)!) - Order doesn't matter
- Permutations: P(n,r) = n! / (n-r)! - Order matters
