For instance, if we have the inequality |x - 5| < 3, it means the distance of x from 5 is less than 3 units.
How it Works
In algebra, the absolute value of a variable represents the distance of the variable's value from zero on the number line. Think of it as a measure of how far away a number is from zero, without considering direction. For example, if we have the absolute value of x, denoted as |x|, it means we're looking at the distance of x from zero, regardless of whether x is positive or negative. This concept is crucial in solving equations and inequalities, particularly those involving absolute value.
