11.6.2 Translating Words to Symbols
Practical problems seldom, if ever, come in equation form. The job of the problem solver is to translate the
problem from phrases and statements into mathematical expressions and equations, and then to solve the
equations.
As problem solvers, our job is made simpler if we are able to translate verbal phrases to mathematical
expressions and if we follow the ve-step method of solving applied problems. To help us translate from
words to symbols, we can use the following Mathematics Dictionary.
