Term | Definition |
Identify property of addition | *it has a zero in it
*regular problem
*simple
* 66 + 0 = 66 |
Commutative property of addition | * it is the same problem on both sides
*flipped the numbers
*we get the same answer on both sides
* 16 + 7 = 7 + 16 |
Commutative property of multiplication | * the same equation on both sides
*numbers are switched
*both sides of the equation get the same answer
* 5 X 6 = 6 X 5 |
Associative property of multiplication | * parenthesis
*same equation on both dies
* flip flop the parenthesis
* 7 X (2 X 3) = ( 7 X 2) X 3 |
Distributive property | * parenthesis
*same equation on both sides
*sharing one or more numbers
* 3 X (1 + 2) = (3 X 1) + (3 X 2) |
Identity property of multiplication | * same answer on both sides
* using the number one
*simple
* 6894 X 1= 6894 |
Associative property of addition | * parenthesis
* same equation on both dies
*switched the parenthesis around the numbers
* (2 + 4) + 6= 2 + (4 + 6) |
equation | a math problem that includes an equal sign, both sides of the equation are equal |
