| Reflexive |
7=7, a=a |
| Symmetric |
if a=b, then b=a |
| Transitive |
If a=b and b=c then a=c |
| Zero Property |
a*0=0 |
| Distributive Property |
a (b+c)=ab+ac |
| Additive Inverse |
a+-a=0 |
| Additive identity |
9+0=9 |
| Communitive property of + and * |
a+b=b+a, ab=ba |
| Multiplicative Inverse |
b*1/b=1 |
| Multiplicative Identity |
12*1=12, x*1=x |
| Associative Property of + or * |
(a+b)+c=a+(b+c) |
| Substitution |
