A U.S 1040 individual tax return form with a pencil lying on top of it


Have you ever had to fill out a tax form when starting a new job or filing your tax return at the end of the year? It can be a puzzling task, with lots of instructions such as “enter the sum of line 20 and line 32 into line 33” or “enter the difference between line 8 and line 9 into line 10.” The form might be telling you to do simple addition or subtraction, but it’s not always obvious due to the wording used. In this section, you’ll learn how to untangle algebraic expressions by identifying and combining like terms and translating words and phrases into familiar operations.

Before you get started in this module, try a few practice problems and review prior concepts.
