Back to the pastDiscrete Mathematics Level pending
A man deposits a 10000 dollar in a bank, where the annual compound interest is 2%. He claims that if he invents a time machine, going back to the past and collect interest given by the bank in the previous year, he could obtain (10000 *[(2%)^ (-1)] ) , a total of 500000 dollars, is that right? If not, what is his actual loss (or gain) ?
Reminder: Input 0, if it is right.
