  1. Commutative Property
    • Two numberscan be added or multiplied in different orders. 
    • a+b=b+a, and ab=ba
  2. Associative Property
    Allows you to group numbers in different ways when multiplying or adding

    (ab)c=a(bc) and (a+b)+c=a+(b+c)
  3. Distributive Property
    • Has to do with distributing multiplication over each term inside the parenthesis. According to this property a(b-c)=ab-ac
    • a(b+c)=ab+ac
  4. Identity Property
    • For multiplication involves multiplying a number by 1, which does not change that number. In other words, 1*a=a*1=a.
    • For addition involves adding 0 to a number, which does not change that number. In other words, a+0=0+a=a
  5. Inverse Property
    • For multiplication states that every nonzero number has a multiplicative inverse such that when the two are multiplied, the result is 1. 
    • a(1/a)=1

    Similarly, every number has an additive inverse such that when the two are added, the result is 0. In other words, a+(-a)=0
