Just like doing math homework
on September 16, 2013
As a puzzle fan, I bought this expecting math-related riddles. I shouldn't have, nor should you unless you're that guy who's faster at math than a calculator, because while there are some good mathy riddles, the problems are primarily the kind of math that requires visual calculation [using coins, dominoes, etc.] vs. doing it in your head; even the "Mathematics with Almost No Calculations" chapter I found I needed to work it out on paper. This is fine, but it feels a lot less recreational if I need to use a notepad, especially if I don't have one handy. Furthermore, this is a translation, so there are a few puzzles that are confusing/don't work out as smoothly in English, though I was disappointed to find some glaring typos--e.g., "7/12 = 1/3 - 1/4" [maybe if you ADD them!]. On the whole, it's an interesting thought exercise and forces me out of my comfort zone in trying to solve the puzzles, but I found it most useful as a sleep aid.
