Absolute value is the distance a number is from zero. In other words, if your number is 45, then the number is 45 places away from zero. If your number is -45, then your absolute value is still 45, because -45 is 45 places away from zero. Absolute value often comes up in geometry problems, so knowing the basics on how to find the absolute value will help you solve these equations.
