Like and unlike terms

Like and unlike terms

In algebra, like terms are two or more terms that have the same variables and/or powers. The coefficient do not matter. [cite web |url=http://www.math.com/school/subject2/lessons/S2U2L4DP.html |title=Like terms In Depth |accessdate=2008-09-07 |work=Math Online |publisher=Math Online] Similarly, unlike terms do not have the same variables and/or powers. The order of the variables does not matter unless there is a power. For example, 8xyz^2 and -5xyz^2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all constant terms are like terms.
