  1. Sum
    Answer to an addition problem

    Ex. 3+5=8
  2. Product
    • Answer to a multiplication problem
    •   Ex. 3x5=15
  3. Difference
    Answer to a subtraction problem

    Ex.  7-3=4
  4. Quotient
    Answer to a division problem

    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
    Any number that ends in 0,2,4,6,8


    Ex. 28
  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
  16. 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
  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
