Rearrange variables - practice problems

Work with mathematical expressions. Expressions are mathematical objects where some numbers are replaced by letters - variables. For example, the area of ​​a circle is S = π r2, where r is a variable, the radius of the circle, and S is also a variable, the area. This is how we can describe the relationship between area and radius for all circles, generally. We can modify expressions, simplify, multiply, divide, add, etc. Also known as Formula Manipulation.
