Question

How do you simplify `abs{-28} + abs{+3} -abs {-23} + abs{+76} - abs{+62}`?

Answer 1

See full simplification process below

Explanation:

First, evaluate each of the terms within the absolute value functions. The absolute value function takes any negative or positive number and transforms it into its positive form:

`abs(-28) + abs(+3) - abs(-23) + abs(+76) - abs(+62) ->`

`(28) + (3) - (23) + (76) - (62) ->`

`31 - (23) + (76) - (62) ->`

`8 + (76) - (62) ->`

`84 - (62) ->`

`22`

Answer 2

The valur of this expression is `22`

Explanation:

To write this expression without absolute value signs you have to remember that:

`abs(x)={(x,x>=0),(-x,x<0):}`

In other words if you leave the absolute value sign you change the negative number to positive, and leave positive number unchanged.

`|-28|+|+3|-|-23|+|+76|-|+62|=`
`=28+3-23+76-62=22`
