The answer to the problem is 10 since it is wanting the absolute value of the answer.
Hi!
When numbers are in a box like that, it's their absolute value, which is their distance from 0. So it doesn't matter if it's positive or negative.
Solve.
|-4 + 3 - 9|
|-1 - 9|
|-10|
10
The answer is 10.
Hope this helps! :)
