In this lesson, you used what you know about operations, addition, subtraction, multiplication, and division to write equations from problem situations. You also worked backwards and wrote problems from one-step equations involving addition, subtraction, multiplication, and division.

In a different lesson, you will learn how to solve these equations in order to determine solutions to real-world problems.
