Learn what absolute values are and how to work them in this short, computer animated video. Key concepts covered are: absolute values, distance from zero, number lines, and writing and reading absolute values. The video ends with a 10 question, fill... in the blank quiz.[more]

In this video, the instructor defines absolute value and shows a variety of examples to practice the concept. Examples range from very simple to more complex.

Sal Khan offers an example of solving an absolute value equation. Mr. Khan uses the Paint Program (with different colors) to illustrate his points.

The first thing that is discussed in this video is the definition of absolute value. Absolute value actually represents distance and is always positive, the symbol of an absolute value is the two bars around the value. Distances are always positive t...hat is why absolute values are always positive. They show absolute value using a number line. Many examples are given, when an equation is between the two bars it means the answer should be in absolute value terms. Then they discuss the opposite of a number. Then they show how to ask what the opposite value is in math equation terms. They explain the opposite of a positive number is like multiplying the number by negative one. They also show the opposite of a positive and negative absolute value. Video is good quality and good for all students as review or initial learning of the concept.[more]

This video explains how to evaluate expressions involving absolute value. The examples include a few very basic problems involving simplifications with absolute value. (03:16)

Absolute values are always positive. The absolute value of a negative number is positive. THe absolute value of a postitive number is positive. This video helps explain this concept using a white board and narrator.
