Question

How do you simplify `abs(-18)`?

Answer 1

`18"`

Explanation:

`"the absolute value always returns a positive value"`

`"this is because it gives a measure of the distance a number"`
`"is from the origin and distance is always positive"`

`"for example "|-4|=|4|=4`

`"since both - 4 and + 4 are 4 units distance from the origin"`

`rArr|-18|=18`
