I am not sure what I am doing wrong

def mod(a, b) print a % b end

I am confused as to why this is not the correct solution for getting a remainder of a when divided by b

method.rb 
def mod(a, b)
  print a % b
end

From what I understand, the print function is used primarily to print strings on your screen, it does not do any math. However you can print out a VARIABLE* containing math operations.

def example(a, b)
  variable = a % b
  print variable   // Print can only be used either with "" to represent strings or with a variable.
end

Or you can use the return function to return a value.

def mod(a, b)
  return a % b
end

It's asking you to return the remainder, not print it
