### About This Chapter

## NES Middle Grades Math: One-Step Equations - Chapter Summary

The video lessons contained in this section of the NES Middle Grades Math course are designed to give your brain a reminder of everything involved in one-step equations. You will have a chance to go over the basic operations involved in writing and solving the following types of problems:

- One variable addition equations and word problems
- Subtraction equations and word problems with one varibale
- Multiplication and division one variable equations and word problems
- Inverse operations
- Using algebra tiles to solve equations

Each of the lessons includes an engaging video, text transcript and self-assessment quiz. If you need to step away from the computer for a while, you can print the quiz results to take with you and review the answers at any time during the day to get you prepared to take the NES Middle Grades Math exam.
