In mathematics, the absolute value or modulus |x| of a real number x is the non- negative value of x without regard to its sign. Namely, |x| = x for a positive x, |x| ...
More Examples: The absolute value of −9 is 9; The absolute value of 3 is 3; The absolute value of 0 is 0; The absolute value of −156 is 156 ...
One easy way to think of absolute value is the distance it is from zero. To do that, a number line comes in handy. Watch and learn.
Before we start sticking a bunch of x's in these things, let's remember what they are. Look at a few examples:
Shows you the step-by-step solutions solving absolute value equations! This calculator will solve your problems.
There is a technical definition for absolute value, but you could easily never need it. (If you go as far as calculus, the technical definition might come up.) For now ...
Demonstrates how to solve absolute-value equations, and explains the reasoning behind the algebra. Also compares algebraic results with graphical results.
In this tutorial you'll see how you can think of absolute value in a very intuitive way. Let us know if you have any questions about it!
The absolute value of a number is its distance from zero on a number line. The absolute value of x is written as |x|. For instance, 4 and -4 have the same absolute ...
