Adding/ Subtracting Polynomials :
To add two polynomials , simply add like terms	Use commutative property to get like terms together.
To Subtract two polynomials , change all subtraction to addition, and then add like terms. Don’t forget to distribute the negative !
	Distribute your negative !
Multiplying polynomials :
Monomial by monomial : Use the commutative property and the properties for exponents
Monomial by any other polynomial : just use the distributive property and the rules for exponents
FOIL method (for two binomials only): First, Outside, Inside, Last	Combine like terms
Column method (for other polynomials): Line up like long multiplication, but work from left to right and line up like terms .		Line up like terms, Add
