Khan Academy: Absolute Value as Distance Between Numbers

Young math whizzes write the opposite of the each integer in the first twelve problems. They write the absolute value for each integer in the second set of problems and name a pair of integers with the same absolute value.

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.

A video describes solving a simple absolute value equation.

Practice taking the absolute value of the difference of two numbers to find the distance between those numbers. Apply this principle to solve word problems. Students receive immediate feedback and have the opportunity to try questions...

Solve conceptually challenging absolute value problems. In order to succeed at these problems, you'll need to remember that the absolute value of the difference of two numbers is the distance between those numbers. Students receive...
