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.
Before you can add or subtract fractions, the denominators must be the same. If the denominators are different, you need to find a common denominator by determining the least common multiple of the existing denominators. Once the denominators are equal, you can add or subtract the numerators while keeping the common denominator.
add them or subtract them, as appropriate!
because it would be diffcult to understand.[you don't add or subtract the demonters]
They must have the same denominators.
The opposite of add is subtract.

So that you only have to add/subtract the numerator which makes it much easier.
