Properties of Equality
| Term | Definition |
|---|---|
| Addition Property of Equality | You can add the same number to both sides of an equation, and the statement will be true. |
| Addition Property of Equality | -3 + x = 5 +3 +3 __________ x = 8 |
| Subtraction Property of Equality | You can subtract the same number from both sides of the equation, and the statement will be true. |
| Subtraction Property of Equality | x + 7 = 14 -7 -7 ____________ x = 7 |
| Multiplication Property of Equality | x/6 = 3 6 * x/6 = 3 * 6 x = 18 |
| Multiplication Property of Equality | you can multiply both sides of an equation by the same number, and the statement will still be true. |
| Division Property of Equality | You can divide both sides of an equation by the same nonzero number, and the statement will be true |
| Division Property of Equality | 6x = 36 6x/6 = 36/6 x = 6 |
| Additive inverse | The opposite of a number. Two numbers are additive inverses if their sum is zero. |
| -5 | What is the additive inverse of 5? |
| associative property of addition | For all numbers a,b, and c (a+b) +c = a + (b + c) |
| associative property of multiplication | For all numbers a, b and c. (a x b) x c = a x (b x c) |
| commutative property of addition | Name the property. 3+4 = 4 + 3 |
| commutative property of multiplication | Name the property. 3(12) = 12(3) |
| Distributive property | What property is used below? 3(4+5) = 3(4) + 3(5) |
