The Solving Simple Interest Problems is a series of tutorials on how to solve simple interest problems. In solving interest problems you need to know the following terms:

the **principal (P)** is the money invested, the **rate (R)** of interest is the percentage of interest (that is the number with percent sign), the **time (T) **and the** interest (I)** is the earnings or return of investment. The interest is the product of the principal, the rate, and the time, or I = PRT is explained in the first part of the series.

**How to Solve Simple Interest Problems Part 1 **discusses the basics of simple interest problems and the terms used in such problems. Two examples worked examples are solved in which interests are both unknowns.

**How to Solve Simple Interest Problems Part 2 **is a continuation of the simple interest discussion. One problem is an example of a rate of interest which is not given yearly and the other one is an investment made for more than a year.

**How to Solve Simple Interest Problems Part 3 **is a discussion of simple interest problems where the unknowns are the principal and the rate.

I will be posting exercises and problems with solutions about this type of problems soon, so keep posted.
