Test tomorrow over Chapter 7.
Don’t forget to study math properties.
Commutative Property of Addition—if the order of terms changes, the sum stays the same. 12 + a = a + 12
Associative Property of Addition—when the grouping of terms changes, the sum stays the same. 5 + (8 + b) = (5 + 8) + b
Identity Property of Addition—The sum of 0 and any number is that number.
0 + c = c
Commutative Property of Multiplication—if the order of factors changes, the product stays the same.
d x 9 = 9 x d
Associative Property of Multiplication—when the grouping of factors changes, the products stays the same.
11 x (3 x e) = (11 x 3) x e
Identity Property of Multiplication—the product of 1 and any number is that number. 1 x f = f
Distributive Property—multiplying a sum by a number is the same as multiplying each term by the number and then adding the products.
5 x (g + 9) = (5 x g) + (5 x 9)
