Question

How do you evaluate `abs(9-5)-abs(6-8)`?

Answer 1

`2`

Explanation:

The `color(blue)"absolute value"` is always `color(red)"positive".`This is because it gives a measure of how far a value is from zero.

`rArr|-4|=|4|=4` since - 4 and 4 are both 4 units from zero.

`rArr|9-5|-|6-8|=|4|-|-2|=4-2=2`
