Introduction
Formulas can be extremely useful tools in mathematics. There are hundreds and hundreds of different formulas that can all be used to apply mathematics in a real-world context.
Formulas are nothing more than equations that give a relationship between two or more variables (or letters). Some examples of formulas include
- Area of a Rectangle: A = lw
- Perimeter of a Triangle: P = 4s
- Interest Earned on a Bank Account: I = Prt
When formulas are not in a useful form, this could pose a problem. But have no fear because we have algebra! As we have been solving equations using the four basic operations of adding, subtracting, multiplying, and dividing, we can also apply these operations to different formulas to write them in a useful form.
