5th grade math vocabulary

Inverse Operation Operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Factor Numbers we can multiply together to get another number. Example: 2 and 3 are factors of 6, 2 × 3 = 6
Factor Pair A pair of numbers that, when multiplied will result in a given product ( or the same product ). Example: (1 x 12)(2x6)(3x4) are the factor pairs of 12
Product The result of multiplying, or an expression that identifies factors to be multiplied.
Operations addition, subtraction, multiplication, division
Prime Number A whole number greater than 1 whose only factors are 1 and itself.
Composite Number A whole number that can be made by multiplying other whole numbers. Example: 6 can be made by 2 × 3 so is a composite number.
Array An arrangement of objects, pictures, or numbers in columns and rows
Even Number An integer which is "evenly divisible" by two.
Odd Number An integer which is not a multiple of two; A number that when divided by two, leaves a remainder.
Integer A whole number (not a fractional number) that can be positive, negative, or zero.
Whole Number Positive numbers, including zero, without any decimal or fractional parts.
Commutative Property The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2.
Square Number is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.
Multiples a number that can be divided by another number without a remainder
