When you’re learning how to divide algebra expressions in Year 7, it can really help to follow some easy steps. Here’s a simple way to do it:

1. Find the Expressions: First, look at what you’re dividing. For example, if you have $A/B$, that’s your expression.

2. Make it Simpler: Try to break it down into smaller pieces. If you have $x^2 - 4$ and you want to divide it by $x - 2$, you can rewrite it. You can factor $x^2 - 4$ to $(x + 2)(x - 2)$, so now it looks like $(x + 2)(x - 2)/(x - 2)$.

3. Cancel Things Out: If you see any parts that are the same in the top and the bottom, you can cancel them. Just be careful and remember if there are any rules about what values you can't use!

These steps make dividing algebra expressions a lot easier and less scary!
