Combining Like Terms in Algebra

This video tutorial explains how to combine like terms in algebraic expressions. It covers the definition of like terms, which are terms with the same variable and exponent, and provides examples of combining like terms with numbers and variables. The tutorial also includes practice problems to reinforce the concept, emphasizing that terms with different variables cannot be combined.

What does it mean to combine like terms?

• Subtracting constants from variables

• Multiplying terms with different coefficients

• Putting together terms with the same variable

• Adding different variables together
