Product
 Answer to a multiplication problem
 Ex. 3x5=15

Difference
Answer to a subtraction problem
Ex. 73=4

Quotient
Answer to a division problem
Ex. 9÷3=3

Divisor
A number by which another number is to be divided
Ex. 15÷3=5

Dividend
The number that is being divided
20÷5=4

Prime
A number that can only have factors of 1 and itself
Ex. factors of 5 1,5

Composite
A number that has factors other than 1 and itself
Ex. factors of 6 1,2,3,6

Odd
Any number that ends in 1,3,5,7,9
Ex. 39

Even
Any number that ends in 0,2,4,6,8
Ex. 28

Factor
Factors are numbers you can multiply together to get another number
Ex. Factors of 16 are 1,2,4,8,16

Multiple
A number that can be divided by another number without a remainder
 Ex. First 5 multiples of 7 are
 7,14,21,28,35

Greatest Common Factor (GCF)
 The highest number that divides exactly into two or more numbers
 Example: the GCF of 12 and 30 is 6, because 1, 2, 3 and 6 are factors of both 12 and 30, and 6 is the greatest.

Least Common Multiple (LCM)
The smallest number that is a multiple of two or more numbers. Example: the Least Common Multiple of 3 and 5 is 15

Distributive Property
You get the same answer when you multiply a number by a group of numbers added together as when you do each multiplication separately Example: 3 × (2 + 4) = 3×2 + 3×4

Add
To bring two or more numbers (or things) together to make a new total. Here 1 ball is added to 1 ball to make 2 balls

Subtract
Taking one number away from another
Ex. 41=3

Multiply
Repeated addition. For example: 5 × 3 = 5 + 5 + 5 = 15

Divide
To divide is to split into equal parts or groups.
Ex. 8 divided by 2 = 4

Equivalent
When something is the same
Ex. 8/8 = 1

MultiDigit
 More than one digit
 Ex. 36

Divisibility
When one number can be divided by another and the result is an exact whole number. Example: 15 is divisible by 3

Numerator
The top number in a fraction, shows how many parts we have.
Ex. 7/8 7 is the numerator

Denominator
 The bottom number in a fraction. Shows how many equal parts the item is divided into.
 example 3/4, 4 is the denominator

Mixed Number
A mixed fraction is a whole number and a fraction combined into one "mixed" number. Example: 1½ (one and a half) is a mixed fraction
