Combining Like Terms

What are like terms?

• Terms with different coefficients

• Terms that are both constants

• Terms with the same variables to the same powers

• Terms with different variables

What does combining like terms allow us to do?

• Increase the number of terms

• Simplify expressions

• Change the value of the expression

• Make expressions more complicated
