Before you can add or subtract, the quantities involved must be expressed in the same units or form. For example, if you are adding lengths, both measurements must be in the same unit, such as meters or centimeters. Additionally, when dealing with algebraic expressions, the terms must be like terms, meaning they should share the same variable and exponent. Only then can you combine them appropriately.

What condition must be met before you can add or subtract fractions?
