More often than not, problems involving math appear as word problems instead of an equation or expression. In order to solve meaningful real-world problems, you need to be able to translate a word problem into a mathematical expression or equation. In this lesson, you will examine a variety of ways that you can do just that.

One thing to keep in mind is the order of operations, which you have learned in previous grades. In the interactive below, click each letter in the acronym, PEMDAS, to remind yourself about the order of operations.

In this lesson, you will focus on applying operations, including the order of operations, to solve real-world problems. You will also perform those operations on both positive and negative numbers and justify the selection of a given operation.
