Question

How do you simplify `abs(11-pi)`?

Answer 1

`abs(11-pi) = color(blue)(11-pi)` or, approximately, `color(blue)(7.85841)`

Explanation:

`pi` is just a number which is less than `11`

So
`color(white)("XXX")11-pi > 0`
and
`color(white)("XXX")abs(11-pi) = 11-pi`

Using the approximation `pi=3.14159`
`color(white)("XXX")11-pi=7.85841`
