The author of this book contacted me as I've previously read similar ones about improving my mental maths. I'm always keen to learn new tricks to make sums simpler to do, and gave it a go.
This is a short book, only an hour or two to complete from cover to cover. And boy, did I get a surprise! Some tricks I've never seen before but so simple it's crazy! Suddenly some rather long sums are achievable mentally in a just a couple of seconds.
In my edition were a few errors that the author assures me are now corrected, but even these didn't detract from the mental tricks he explains.
The language does sometimes require a re-read as it can be a little wordy (translated from the author's first language I believe).
But the maths is so astonishingly easy in the majority of chapters that you feel instantly buoyed up by how simple maths can be.
I admit to having my favourite parts, and did skim a few tricks in division and multiplication. The long sums there I have no need of in my everyday life, whereas addition and subtraction and selection tricks in mult/division would be useful.
The chunking method was brilliant, multiplying by 11, left to right and digital roots, decomposing. Each is explained with a few examples (more would help retention though) and I could see a use for this in my work and home dealings.
The use of Euros didn't really bother me, it's still the same number.
I think the book could have been longer though, the book I got a lot from (Rapid Maths Tips and Tricks) was more thorough in its approach. But this book will give confidence in just a few minutes.
And you'll get a party trick or two out of it as well.
With thanks to the author for the review copy.
