I've been doing a lot of internet research on maths for next year's class, and I particularly love this guy. He has explained Fibonacci numbers, fractals and heaps more to me, better than any maths teacher I've ever had. So when I stumbled upon his Life Skills lectures, I had to watch. This is really good advice, and I've found that I have actually done this without realising. If anything in maths is a mystery to you, this is the man to educate you.
