It is used in interest theory. Thus a(0)=1 and the value at time t is given by: = (). where the initial investment is (). For various interest-accumulation protocols, the accumulation function is as follows (with i denoting the interest rate and d denoting the discount rate):

Here’s a simple example of how compound interest works. Say you deposit $10,000 into a savings account that has a 2% APY. At the end of one year, you’d have $10,202, assuming that interest ...
Richard Witt's book Arithmeticall Questions, published in 1613, was a landmark in the history of compound interest. It was wholly devoted to the subject (previously called anatocism), whereas previous writers had usually treated compound interest briefly in just one chapter in a mathematical textbook. Witt's book gave tables based on 10% (the ...
