You can use Ruby to perform mathematical calculations. The four standard operators are probably familiar to you:
Two other less-familiar but important operators are
** is used for exponents;
5**2 is 5 to the power of 2, which is 25.
% is a little weird. In Ruby, it isn't percent, it is modulo. Modulo is like division, but it gives you just the remainder of a division problem.
moduloAnswer=5%2 #moduloAnswer=1 exponentAnswer=2**3 #exponentAnswer=8
Use math operations to turn old variables into new ones that the if statement will print true to the console when run.
