I have two question first why is this not working and why did he use (int) beofre Math.pow().
Thank You
Math.pow returns a double.
To store it in an int variable you have to typecast it to int {putting (int) before the value}
typecasting a double to an int removes all the digits after the decimal.
12.25 becomes 12
13.99 becomes 13
14.00 becomes 14
