Solution - Absolute value expressions

Absolute value can be used to measure the difference from one point to another, regardless of the direction of movement. This is because distance is not represented in negative numbers but rather by direction, such as forward/backward, east/west, above/below (e.g., 40 meters below sea level). It can also help solve problems that require positive numbers or involve inequalities. Absolute value can be used to convey a change in quantity that cannot be negative. This is especially applicable in everyday situations, in which we seldom use the word "negative" to refer to amount, opting instead to describe the movement’s direction.
