Combining Like Terms

Terms  Are separated by a sign (- or +)

How many terms are in the example?

Coefficient  it is the number next to the variable. You must have a variable to have a coefficient.

Any variable without a number in front of it has an understood coefficient of 1.

Constant  a number without a variable
