| Union | To bring together 2 or more sets |
| Intersection | To bring together what is in common between 2 or more sets |
| Absolute Value | The distance of a number from the origin |
| 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) |
