Remember those pesky little numbers called powers that turned out to be powerful little numbers? I'm sure you do - they play a key role in KS3 Maths, especially when working on algebra.
Powers are the small numbers written above and to the right of other numbers. You'll be most familiar with squares (2) and cubes (3) but any number can be a power. For example, 1 million (1,000,000) is 106 (with ten, the number of zeroes is a clue to its power).
So, just to make sure that you are comfortable with powers, here is another quiz on the subject. It's designed to give you some more practise at using algebra and powers together. Take your time and read each question carefully before submitting your answers. And don't forget to read the helpful comments after each question - they can help to clear up anything you were unsure of. Good luck!
