Book Chapter
This first chapter starts off with addition, subtraction, multiplication, division, fractions, and a few other things. It gives a demonstration of the basic differences between memorizing rules and really understanding the process. For those who te...

Given that the vast majority of people reading this book will never ever have to teach calculus, you might be wondering why in the world the topic is being addressed here. Well, even though you might not teach calculus, chances are that when teachin...
Book Chapter
This chapter deals with fractions and decimals. This is one place where people who are otherwise fine with math jump off the boat and decide it's just too weird to continue. As with everything else, though, it's only a matter of understanding what'...
Book Chapter
This chapter contains basic material related to exponents that is a supplement to Chapters 1 and 2. Keeping with the theme of the first two chapters, there will be a discussion of procedures for which one may know the rules, but might not understand...

This chapter is all about negative numbers, and how to deal with them. They're not all that difficult to understand, but for some reason people get just a little uptight when they see computations involving negative numbers. I'm guessing that the a...

Why Do They Have to Gum Everything Up With Those Letters?
Often people who are relatively comfortable doing math with numbers completely freak out when variables (you know, those letters that take the place of numbers) come into the picture. Things start looking much more abstract and complicated. You don...

All Things Being Equal...Or Not
Now that we've covered at least a few examples of how we get equations from the physical world, it's time to work on solving those equations. Solving an equation means figuring out what values of the unknowns (the variables) will make the equality a...

Pie are not Round; <i>π</i>²
What would a math book be without a nerdy math joke? Bad joke aside, you might recognize π² as the formula for the area of a circle. And you might infer from that fact that this chapter addresses geometry. Often people think of geometry as a b...
Book Chapter
Most textbooks go through the procedures for solving math equations before they ever get to word problems, which is a bit backwards. You should know where the equations come from in the first place, so you might actually have a reason for solving th...
