Question

How do you evaluate `abs(-32 )`?

Answer 1

`|-32|=32`

Explanation:

`|-32|` is the absolute value or modulus of `-32`. Absolute value or modulus of a real number is always positive i.e. without its sign (i.e. negative or positive) and in value is equal to just physical value of the number under consideration.

So `|-32|=32`.

Note - It is also defined as `|a|=a` if `a>=0` and `|a|=-a` if `a<0`. Here as `-32<0`, `|-32|=-(-32)=32`.
