In this module you can study how to substitute given values into a formula.
For example, you'll learn how to find the perimeter of a square (the formula for this is p=2w + 2l) when you know the width is 10m and the length is 20m.
Working with linear equations (equations with no squares or roots)
In this module you can study how to change an equation around so that any variable is by itself on one side of the equal sign.
For example, you will study how to change this P = 2W + 2L into this: W = (P - 2L) / 2
