One of the things we learned this week in Precalc 11 is the absolute value and it is defined as the principal square root of the sequence of a number. It is the distance of the number from 0 on the number line.

The absolute value of a number is always positive.
Ex.
= 10

=.

But if the negative is outside the absolute value bars the answer can be a negative.
Ex.
– = -20
The absolute value is -20 because the absolute value of is 20 and there is a – in front so the answer is -20.

Those are just simple questions, absolute value equations can sometimes be more complex.
