RF2.7 : I can solve an equation with a single absolute value algebraically. We say that –5 and 5 have the same absolute value. Absolute value is like a clock it has only positive numbers. a month ago. We'll still follow the same plan, so absolute value of anything equals something else. We now proceed to solve each equation independently. Absolute value is talking about numbers so it must be positive. In mathematics, absolute value of a number refers to the distance of a number from zero, regardless of direction. Absolute Value Equations on Brilliant, the largest community of math and science problem solvers. Next lesson. 2. Do not make the common mistake of just turning every minus sign inside the absolute value bars into a plus sign.
