Formulas describe the constant (unchanging) relationship between two or more values. For example, π is the constant relationship between the diameter and circumference of a circle. Math formulas express relationships by using variables. If we know a value for every variable but one, we can substitute values in place of the variables we know, and solve for the unknown value. These formulas are printed in the GED® test booklet. This lesson should take approximately 2 hours to complete, if all components are utilized.
