Absolute Value

Absolute value refers to the distance between a number and zero on the number line, regardless of direction. It measures how far a number is from zero without considering whether it's positive or negative. For example, the absolute value of both 5 and -5 is 5 because both are 5 units away from zero. It’s represented by two vertical bars, like |x|, symbolizing that we only care about the size of the number, not its sign. Absolute value is useful in situations involving distances, differences, or magnitudes where the direction doesn't matter.
