| Division Property of Equality | If a = b and b doesn't equal 0, then a/c = b/c |
| Substitution Property of Equality | If a = b, then b can be substituted for a in any expression. |
| Distributive Property | a(b + c) = ab + ac |
| Reflexive Property of Equality | a = a |
| Symmetric Property of Equality | If a = b, then b = a |
| Transitive Property of Equality | If a = b and b = c, then a = c |
