I don't just teach, you know. As part of my mission of bringing maths joy to as many people as possible, I also write extensively about maths.
There's the Flying Colours Maths Blog of course, where I guide you through the Secrets of the Mathematical Ninja; give you pro tips about acing A-level maths; throw out my favourite mathematical quotations and invite you to ask me questions. Check it out!
I'm also the author of several maths books, which you can get hold of below:
Whether you're trying to get your maths skills up to scratch for your own enjoyment, to pass an exam or to help your kids with their homework, Basic Maths For Dummies guides you through the tricks of the trade and helps you overcome the fear of maths.
