3x is the magic number.
In this test you need to type in the most simplified version of each algebraic expression you are shown. There's no time limit AND you get more than one go at getting each one right. Ready?
The quiz will accept various formats for each answer, so if you think you're right but it says you're wrong, try writing it a different way! If you need to write indices, you can just put e.g. x^2 for x² to make things easier.
