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
