Ever wish you'd paid more attention in math class? Remember all the stuff the teacher was trying to tell you? About ratios and prime numbers, calculating the area of a triangle- and wasn't there something in there about the Pythagorean Theorem? But now you can see there was a point to it all. It would be great to calculate the percentage of sales tax on a big purchase. The problem is, you can't remember any of the formulas. Here's a handy guide to all the math you forgot in school - from useful algebra equations to the math you'll need to figure out the tip the next time you dine out.
