exponents.
^2
Add the coefficients of like terms.

^1
Like terms have identical variables and 
exponents.
^2
Subtract the coefficients of like 
terms.

@22 Multiplying Monomials
%3
^1
Multiplication is commutative (the 
order doesn't matter).
^2
Group coefficients and similar 
variables together.  
^3
Simplify by multiplying coefficients 
and adding the exponents of like 
variables.
~
%4
^1
When a monomial term in parentheses is 
raised to a power, raise each part of 
the monomial to the power indicated.
^2
Raise monomials to indicated powers.
^3
To raise variables with exponents to a 
power, multiply the two exponents.  
Simplify non-variable terms with 
exponents as usual.
^4
Simplify by multiplying coefficients 
and adding the exponents of like 
variables.

@32 Multiplying Polynomials
%3
^1
By using the Distributive Property, the 
product of a monomial and a polynomial 
can be written as a sum.
^2
Rewrite the multiplication expression 
as a sum, multiplying each term of the 
polynomial by the monomial outside the 
parentheses.
^3
Simplify each product.

%4
^1
The FOIL (First, Outer, Inner, Last) 
method helps you multiply two 
binomials. 
^2
Use the FOIL method.  
Multiply the First terms of each 
binomial, then the Outer terms, then 
the Inner terms, and finally the Last 
terms.  
Rewrite the expression as a sum.
^3
Find each product.
^4
Simplify and combine like terms.
