Theory

Write as a difference of fractions

If the numerator of a fraction is a difference it can be rewritten as difference of fractions. The denominator is the same, and the numerators are the terms in the difference of the original expression.

\frac{8 - 5}{3} = \frac{8}{3} - \frac{5}{3}

This is the same rule as when subtracting fractions, but the other way around.
