Simplifying Expressions with Like Terms
6th Grade•15 minutes
Learning Objective
I can simplify expressions by combining like terms.
Key Concepts
Like terms have the same variables to the same powers.
When combining like terms, we add or subtract the coefficients, which are the numbers in front of the variables.
To simplify expressions, you can rewrite subtraction as adding the opposite to make it easier to identify negative terms.
