Even those who find algebra easy are stumped by word problems (also called ‘‘applications’’). In this book, word problems are treated very care- fully. Two important skills needed to solve word problems are discussed earlier than the word problems themselves. First, you will learn how to find quantitative relationships in word problems and how to represent them using variables. Second, you will learn how to represent multiple quan- tities using only one variable.
