What each property means
Question | Answer |
---|---|
Additive Identity | For any number the sum of that number and 0 is the that number. Example: 2+0=2 |
Multiplicative Identity | For any number the product of that number and 1 it that number. Example 5x1=5 |
Additive Inverse | Two numbers with a sum of 0 Example 4+(-4)=0 |
Multiplicative Inverse | The product of any fractions and its reciprocal is 1. Example 9/1x1/9=1 |
Multiplicative Property of Zero | For any number the product of that number and 0 is 0. Example 7x0=7 |
Reflexive Property of Equality | Any quantity is equal to itself. Example 25=25 or 1+3=1+3 |
Symmetric Propery of Equality | If one quantity equals a second quantity then the second quantity equals the first. Example 6=3+3,then 3+3=6 |
Transitive Property of Equality | If one quantity equals a second quantity and the second quantity equals a third quantity, then the first quantity equals the third quantity |
Substitution Property of Equality | A quantity may be substituted for its equal in any expression. Example If n=15 then 3n=3x15 |
Communitive Property of + | The order in which you add or multiply numbers does not change their sum or product. Example 9+2=2+9 or 14x2=2x14 |
Associative Property of + | The way in which you group 3 or more numbers when adding or multiplying oes not change their sum or product. Example 1+(2+3)=(1+2)+3 or (2x3)4=2(3x4) |
