**Word problems** do not come with equations. To solve a word problem, it is often helpful to rewrite the problem using mathematical notation.

Here are some strategies for approaching a word problem:

- Always start off by reading the entire problem.
- List information you know and assign variables to anything you don't know.
- Identify what the problem is asking for.
- Look for key words to identify which operations you will need to use. Here are some examples:

\[\begin{equation} \begin{array}{ll} \textbf{Addition: } & \text{more than, increased by, total of, sum} \\ \textbf{Subtraction: } & \text{less than, subtract, difference } \\ \textbf{Multiplication: } & \text{times, product of, multiplied by} \\ \textbf{Division: } & \text{per, quotient of, percent, ratio of} \\ \end{array} \end{equation}\]

(Please note that these examples do not represent a complete list of key words.)
