Ruby Ruby Basics (Retired) Ruby Methods Method Returns: Part 2

This code works in my IRB, but not in the work space. Frustrating.

Why isn't the workspace respecting this syntactically correct ruby?

method.rb 
def mod(a, b)
  c = a % b
  puts "The remainder of #{a} divided by #{b} is:#{c}"
end

puts mod(10, 5)

While your code certainly is syntactically correct, it is not doing what the challenge requested.

The challenge specifies that you have to return a string from the function. You are printing the string with puts which is not the same thing. Even though those actions appear to behave similarly in the REPL.

If you change puts to return like this:

def mod(a, b)
  c = a % b
  return "The remainder of #{a} divided by #{b} is:#{c}"
end

puts mod(10, 5)

Then your code will work.
