Math Whizz is one of my favorite maths website. It doesn't only give you questions it also shows you some new strategies that you could learn from.
It has Touter and replay too.
Touter could show you new things that you haven't learned.
Replay could bring your mind back to what you have learned.But My most favorite thing to do is challenge people on Replay. We could even challenge a whole bunch of people that we don´t even know.
Those are some things that I really love about maths Whizz.
