1 A number divisible by 2. Numbers ending in 0, 2, 4, 6, or 8. even number

2 A number NOT divisible by 2. Numbers ending in 1, 3, 5, 7, 9. odd number

3 When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. (2 x 3) x 4 = 24 2 x (3 x 4) = 24 (2 x 4) x 3 = 24 associative property of multiplication also called the Grouping Property

4 The numbers added together to form a sum. 7 + 8 = 15 addend sum

5 The numbers that are multiplied in a multiplication problem. 3 x 5 = 15 factors product

6 sum the answer to an addition problem difference the answer to a subtraction problem product the answer to a multiplication problem quotient the answer to a division problem

7 The property that states that changing the order of the factors does not affect the product. Example: 3 x 5 = 15 and 5 x 3 = 15 commutative property of multiplication
