By definition, what is the absolute value of a number?
AIts distance from 0 on the number line
BIts distance from 1 on the number line
CThe number with its sign removed and doubled
DThe largest digit contained in the number
Answer & Solution
Correct answer: A. Its distance from 0 on the number line
1. The definition measures a distance, not a value with a sign.
2. That distance is always taken from the number back to 0 on the number line.
3. Because distance can never be negative, absolute value is never negative either.
