Terms and Variables

The video tutorial explains the concepts of variables, coefficients, and like terms in mathematical expressions. It defines terms as parts of expressions separated by addition or subtraction. Constants are values that do not change, while variables can change and are usually represented by letters. Coefficients are constants that multiply variables. Like terms have the same variables with the same exponents, and their coefficients can be added or subtracted. The tutorial emphasizes not adding exponents when combining like terms. Examples are provided to illustrate these concepts, and the video concludes with a review of the key ideas.

Describe the difference between constant terms and variable terms.
