Week 3- Absolute Value of a Real Number

This week we started our new unit on Absolute Values.

The absolute value of a real number is defined as the principal square root of the square root of the square of a number. or The absolute value of a real number is the distance from zero on a number line.

|x| The two lines in a math equation represent the absolute value representation.

For example: |-6| = 6

But you can also have expressions inside the lines.

-| – |

-|- 7|  –> Now you find the absolute value of -7

-(7)

-7
