Do you know the old IT/electronics saying that "only intelligent one understand that 1+1 is equal to 10"? Well you might be forgiven for not knowing binary but the problem of illiteracy and especially mathematical type of it is widespread and frankly speaking quite disturbing. Sure, what would a philosophy student need trigonometric functions or logarithmic smoothing of some multi-variable function for you ask yourself and you might be right, yet the problem persists with even more extreme cases and people, whether it's center of the states, europe or australia, can have problems with basic maths. "But it does not concern me!" you say and here's where this book comes in and shows you how very wrong you are. Alright, when you're on a shopping spree and paying with a card that's not so important, but once you get to the coins, change etc. it all starts to be overt. Does it end here? Paulos seems to find even more extreme cases and unearth them for your own reading pleasure and a word of caution... Be it gambling, advertising language, price cuts, the maths has its influence, often very interesting in all of them. With the 'innumeracy' around us, the advert agents can profit with their increased bars on charts, better statistics or almost zero problems answer with the almost stemming from a number you really should understand. They, the puppeteers and other folk, get better money because people either can't read and understand or just plainly do not comprehend the basics of maths. The price reductions of n% for a shopping spree seasons with prices dropped from the original sticker price or one superficially increased just before the discounts basically mean no savings, check the book and you'll find that most cases mean you're paying extra for the adverts and 'how to sell it profitably' collective. People buying dream holidays/homes/objects they cannot afford either financially (and thus the credits come in) or due to time restrictions... Sure, those you pay are happy with the idea of overspending clients and earning extra cash but spending much too much concerns us all. You might think that high school classes were enough... Well you'd still need a bit of college grade knowledge to comprehend all the math presented, though the author tries to put the info forward easily. Believe me and the author when I tell you this after some time with the little-innumeracy afflicted at the university - even those highly educated can be innumeratic, and once this gets to logic and calculus you end up with people who might be responsible for you future but who do not know the difference between 'and' and 'or'. Not to mention 'all' and 'some'. This books discusses the problem with many examples, some rather simple and believable, some however seem really far too fetched even for a news story in a gossipy stand but still taking place according to the author. Once you read it you'll find you really need to conquer those math books you once threw down to the basement and you really need to understand it. The perspective for those who don't is far too severe for anyone to simply sit by and watch what happens. Once you get it, that is by the time you get to the about 50th page, you'll realise that the people around you and people around the world as well need to understand basic math and use it to see how they all are often played by others. Otherwise there will be more than just a tiny grey area of illiteracy, it's going to be a deep rift, wide enough for the inhabitants to hurt you or make you pay the, title mentioned, consequences. Or you might just become a hollywood superstar and have whole support teams you'd pay far too much just to never use your brain cells after contracting them... if you're lucky enough. For others, the book is a good discussion of the problem, of math ruling the world from gambling with casino always winning to black friday sales and the viewpoint is not so addictive as the coffee or tea you'll need to read it over but still worth the time. It's a good word of warning, though the text flow, the language used, the examples presented, it all seems just to similar to other math in the world book offers... The warning innumeracy specific part and its consequences is discussed specifically only in a part of the book, yet by reading it you understand that the whole maths in real life situation throughout the pages is both real and concerning you... It's both showing the applicable laws and allows you to see how many areas of real life are governed by simple mathematical tricks and gimmicks you might have been not very aware of. Is it worth your money? Frankly, I've read a few similar 'math in life' theme books already and it hardly differs not to mention excels at anything. Sure in essence its contents should be known more or less to most men already and the method of information transfer is capable of finding fans, but I'm not one of them. So basically a good read for anyone with an open mind, but if your finances are constricted somewhat you'd be better looking elsewhere.
