Should I be adding puts mod(a, b) after the end portion of the method? what does it mean by nicely formatted string

This is what I have

def mod(a, b)

puts "The remainder of #{a} divided by #{b} is: " puts a % b end

Should I be adding a C value in the def mod(a, b) portion? or just add c = a % b?

method.rb 
def mod(a, b)

  puts "The remainder of #{a} divided by #{b} is: "
  puts a % b
end

You shouldn't be using puts at all. The challenge specifically request that the string be returned. And "nicely formatted string" is just meant to say something that looks a little nicer to the user who gets back the result. See my code for clarification.

def mod(a, b)
  #write your code here
  c = a % b
  return "The remainder of #{a} divided by #{b} is #{c}."
end

And yes, your mod should be calculated and stored in a variable named c.
