Q: What is | -4 |?
UNANSWERED.
The correct answer is D.
A: Those parallel bars | | mean it's an absolute value problem. Think of absolute value as how far a number is from 0. Looking at the number line below, see that the -4 is 4 away from the 0. So, the answer is 4.
TIP: The absolute value of something is always a positive number or 0.
