It must be the would-be-Geek in me, but I was annoyed that I couldn't remember how to do quadratic equations or divide fractions or, more commonly, couldn't remember how to show the growth of something in percentage points. My friends have asked why I would even care, but it did bug me. But I'm bugged no more - this book is great with a simple, clear approach that explains how to do all these things and much, much more. For someone who doesn't usually pick up anything more taxing than a novel or the Sunday Times Supplement, this has become this week's bedtime reading. Now I'm sure Miss Lloyd (my maths teacher) would never have dreamt that was possible.
I may have to work my way through some of the other titles in the series, starting with the English Grammar book. Now, how do I parse a sentence?...
