Introduction
Math word problems (or story problems, depending on where and when you went to school). What topic has caused more hair to be pulled from tender heads, more tears and anguish, and, at the same time, more feeling of satisfaction and accomplishment? When I told friends that I was writing this book, their responses were varied, but none was mild or without a strong opinion one way or the other. Oh, the stories (pardon the pun) I heard. And, lucky you, I’ve taken some of the accounts and incorporated the better stories in this book. Everyone has his favorite word problem, most of them starting with, “If Jim is twice as old as Ted was. . . .” I was never crazy about math word problems until I got to teach them. It’s all a matter of perspective. I’ve taken years (and years and years) of experience of trying to convey the beauty and structure of math word problems to others and put the best of my efforts in this book. I hope that you enjoy the problems and explanations as much as I’ve enjoyed writing them.
About This Book
Math word problems are really a part of life. Pretty much everything is a word problem until you change it into an arithmetic problem or algebra problem or logic problem and then solve it. In this book, you first find the basic steps or processes that you use to solve any math word problem. I list the steps, illustrated by examples, and then later incorporate those steps into the different types of word problems throughout the rest of the book. The same basic techniques and processes work whether you’re doing a third-grade arithmetic problem or a college geometry problem. You’ll see that I use the processes and steps over and over in the examples — reinforcing the importance of using such steps. Because the steps are carried throughout, you can start anywhere you want in this book and be able to either backtrack or jump forward and still find a familiar friend in a similar step. The different types of word problems are divided into categories, in case you’re only looking for help with age problems or in case you’re only interested in interest problems. Most of the examples have a firm basis in reality, but a few are off the wall, just because you need to have a good sense of humor when dealing with math word problems.
