Algebra

Algebra is great fun - you get to solve puzzles!

In a way it is like a game where you get somewhere by running, jumping or finding secret doors, but with Algebra you play with letters, numbers and symbols.

And once you learn some of the "tricks", it becomes a fun challenge to work out how to use your skills in solving each "puzzle".

Before learning Algebra it is good to understand Patterns.
