A number divisible by 2. Numbers ending in 0, 2, 4, 6, or 8. even number
A number NOT divisible by 2. Numbers ending in 1, 3, 5, 7, 9. odd number
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
The numbers added together to form a sum = 15 addend sum
The numbers that are multiplied in a multiplication problem. 3 x 5 = 15 factors product
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
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
