This interest is added to the principal, and the sum becomes Derek’s required repayment to the bank one year later. From abacus to iPhones, learn how calculators developed over time.

Ancient texts provide evidence that two of the earliest civilizations in human history, the Babylonians and Sumerians, first used compound interest about 4400 years ago.
