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

Ex.  7-3=4
4. Quotient

Ex. 9÷3=3
5. Divisor
A number by which another number is to be divided

Ex.   15÷3=5
6. Dividend
The number that is being divided

20÷5=4
7. Prime
A number that can only have factors of 1 and itself

Ex. factors of 5       1,5
8. Composite
A number that has factors other than 1 and itself

Ex. factors of 6     1,2,3,6
9. Odd
Any number that ends in 1,3,5,7,9

Ex. 39
10. Even

11. Factor
Factors are numbers you can multiply together to get another number

Ex. Factors of 16 are 1,2,4,8,16
12. 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
13. 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.
14. 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
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
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
17. Subtract
Taking one number away from another

Ex. 4-1=3
18. Multiply
Repeated addition. For example: 5 × 3 = 5 + 5 + 5 = 15
19. Divide
To divide is to split into equal parts or groups.

Ex. 8 divided by 2 = 4
20. Equivalent
When something is the same

Ex. 8/8 = 1
21. Multi-Digit
• More than one digit
•  Ex. 36
22. Divisibility
When one number can be divided by another and the result is an exact whole number. Example: 15 is divisible by 3
23. Numerator
The top number in a fraction, shows how many parts we have.

Ex.    7/8   7 is the numerator
24. Denominator
• The bottom number in a fraction. Shows how many equal parts the item is divided into.
• example  3/4, 4 is the denominator
25. 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
