Key idea: Properties — same as for whole numbers, mostly
Integers obey:
- **Commutative** for addition and multiplication: a + b = b + a; a × b = b × a.
- **Associative** for addition and multiplication: (a + b) + c = a + (b + c); (a × b) × c = a × (b × c).
- **Distributive**: a × (b + c) = a × b + a × c — and this is true even when a, b, c are negative.
Subtraction and division are NOT commutative or associative for integers (they aren't for whole numbers either). Order and grouping matter.
