Ruby Ruby Basics (Retired) Ruby Methods Method Returns: Part 1

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

def mod(a, b)
  print a % b

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.

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

def mod(a, b)
  return a % b

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

Ty that fixed it
