Adding or subtracting fractions, there is only one thing to remember, the denominators must be the same. Not so fast, there is more to it, like how to find the Least Common Denominator (the smallest number that all denominators can divide into) or how to cancel algebraic fractions.

Symbolab solves algebraic fractions step-by-step. Most important, you will not only get solution steps, but also intermediate steps for the algebraic manipulations such as cancel, expand, factor, etc.
