What is the absolute value of -7?

Explanation:
Absolute value is the distance a number is from zero on the number line, so it is always nonnegative. Since -7 is 7 units away from zero, its absolute value is 7. You can also see this by the rule |a| = a if a is nonnegative and |a| = -a if a is negative; here a = -7, so |-7| = -(-7) = 7.
