| Associative Laws - for addition and multiplication |
|---|
a + (b + c) = (a + b) + c
a(bc) = (ab)c
| Commutative Laws - for addition and multiplication |
|---|
a + b = b + a
ab = ba
| Distributive Laws - for multiplication and division |
|---|
a(b + c) = ab + ac
(b + c)⁄a = b⁄a + c⁄a (provided that a ≠ 0)
