When my 7 year old daughter demonstrated her ability for long multiplication, I realised I ought to brush up on my maths - at least to stay ahead long enough to help with homework when she needs it!

Enter stage Khan Academy - an incredibly useful site I discovered to help me improve upon my secondary school math.

I must admit, I've become quite addicted, and have set myself the goal of completing all the basic challenges before the end of the year.

Calculus will definitely be interesting...
