How do you evaluate #-abs20#?

Answer 1

Use the definition of absolute value to evaluate #|20|#. Then, you add a negative sign to the answer.

The definition of absolute value is how far a number is from #0#. According to that definition, #|20|# is #20# because, on a number line, #20# is #20# spaces away from #0#.

Then, you add a negative sign to the answer. So, therefore, the answer is

#- |20| = - 20#

To evaluate ( -\text{abs}(20) ), first find the absolute value of 20, which is 20. Then, multiply by -1:

[ -\text{abs}(20) = -1 \times 20 = -20 ]

So, ( -\text{abs}(20) = -20 ).
