The question
Question: work out −|−8| + 3.
−|−8| + 3
1 Absolute value
The minus in front of the bars is outside them.
It stays.
Order: ( ) → x² √ → × ÷ → + −
| | = how far from 0
−| |: the minus stays
The bars mean: how far from 0?
That is never negative.
So |−8| is 8.
With the minus in front, that is −8.
= −8 + 3
2 Plus and minus
Start at −8.
Go up 3.
We land on −5.
= −5
So the answer is −5.
Let's look back.
First: absolute value.
Last: plus and minus.
Answer
= −5
