Title: Great Math book
Review: Best of all the authors explain what it is you're doing when you do algebra. Why doesn't it make sense in the real world? Because it's a game. The conventions may seem arbitrary but the rules are not. The authors multiply things like tenors and pigs and divide them by all kinds of non-mathematical things in order to illustrate the logic of mathematical thinking. They also show that people are thinking algebraically even when they don't know they're doing so. This is a great book if you took algebra a long time ago and are not sure you remember the differences between the various mathematical disciplines. It's also good if you are the type who wants everything explained to you in math, rather than taking it on faith. It won't replace the standard textbook, but it will show you how to use it.
