Inequalities Involving Absolute Value

Help pupils to determine whether using square roots is the method of choice when solving quadratic equations by presenting a lesson that begins with a dropped object example and asks for a solution. This introduction to solving by...

Some equations require inverses of multiplication and division. Solving equations use inverse operations to isolate the variable. The video shows how to solve one-step equations involving multiplication and division and works several...

Add and subtract to keep an equation in balance. With the assistance of a balance, the video explains the process of solving an equation. The presentation details how to solve equations that involve addition and subtraction.

Sal demonstrates how to solve an absolute value equation, keeping in mind there are two possible answers.

Combining the skills from the previous videos, particularly inequalities and absolute values, Sal works to solve several new sample problems. He encourages watching the video "over and over," which is good advice for mathematicians of...

This CoolMath resource will help students learn how to solve inequalities and graph them on a number line.

Use this word problem to practice turning words into math. You'll follow the step-by-step process to determine what is being asked and what you'll need to do to solve the problem. A great tutorial for learners needing a little extra help...

The concept of absolute value can be difficult for learners to grasp. Reinforce their understanding of a basic absolute value expression and connect it to solving equations and inequalities. Scholars write two equations/inequalities to...

After reading this inequality word problem, young learners might just skip over it and not even make the attempt to solve it. It seems rather complicated. So watch this video as the teacher explains all that needs to be done to solve...

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a 2-step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...
