Define absolute value: Define the absolute value of a number. The absolute value of a number is the distance of that number from zero on the number line, regardless of direction. It is always a non-negative number.
Apply to −1: Apply the definition of absolute value to −1.∣−1∣ means the distance of −1 from 0 on the number line.
Calculate distance: Calculate the distance of −1 from 0. The distance of −1 from 0 is 1, because if you move 1 unit from −1 towards 0, you reach the point 0.
