Virtual Nerd: Find the Absolute Value of Positive and Negative Numbers

In this absolute value equations worksheet, learners solve absolute-value equations and inequalities. They graph answers on a number line. This one-page worksheet contains 34 problems.

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

Guiding viewers through the addition and subtraction of numbers, this video includes many tips to help new learners internalize the concept of a number line. It clarifies the relationship between positive and negative numbers, including...

Sal reviews absolute value equations by taking viewers through a careful and deliberate problem-solving process. Those who didn't thoroughly understand absolute value during class will appreciate Sal's steady and straightforward...

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...

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

Sal tackles pre-algebra in this series of videos, starting with the concept of negative numbers. Using a number line, he takes the viewer through different practical examples of negative numbers, such as temperature and bank accounts....

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function,...

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...
