Question

What is the absolute value of a number?

a) The distance from the number to zero on a number line
b) The square of the number
c) The number itself
d) The negative of the number

Answer 1

The absolute value of a number is its distance from zero on a number line, always resulting in a non-negative number.

Step-by-step explanation:

The absolute value of a number is the distance from the number to zero on a number line. This means that the absolute value is always a non-negative number, regardless of whether the original number is positive or negative. For instance, the absolute value of both -5 and 5 is 5 because each is 5 units away from zero on the number line. This concept is important in understanding numerical distance and is key in solving many algebraic equations.
