Exploring Compound vs. Simple Interest

The video tutorial explains how interest is calculated for both borrowing and investing. It covers the concepts of simple and compound interest, highlighting the differences between them. The tutorial provides step-by-step instructions for calculating simple interest using the formula I = PRT, and compound interest using the formula A = P(1 + R)^T. Examples are provided to illustrate the calculations, and the importance of converting percentages to decimals is emphasized. The video concludes with a comparison of the total amounts accrued through simple and compound interest.
