By the end you can

🔍

Tell like fractions from unlike ones

🧩

Factorise denominators and find their LCM

➕

Add and subtract algebraic fractions

✂️

Cancel the answer to its simplest form

🟰Like fractions

Same denominator

Work on numerators only

\( \frac{x}{x-y} + \frac{y}{x-y} = \frac{x+y}{x-y} \)

↔️Unlike fractions

Different denominators

Rewrite over the LCM first

\( \frac{x}{x-y} - \frac{y}{x+y} \)
