Engaging, Entertaining, & Educational

This was a fantastic book. My kids 10, 12, 14 who have been on a "we hate math" phase for a while have actually enjoyed the book. Jason keeps it light and humorous, while still conveying the basic tips in an easily understandable way. As my daughter said, "it's easy when HE explained it"

Actually quite good.

To be honest it's actually better than expected. Especially for 50p great on brushing up on mathematics.

Useful to refresh your memory.

Also, the narrator has refined his style; expect to be fairly engaged. Three words remaining.
