I have a feeling it's very obvious... pardon me! What am I doing wrong?

Which two arguments should be beside mod? How do I say a%b=c in a valid way?

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

Hey Ana,

You are on the right track, but there are 3 little things:

  1. You have an unneeded puts statement (that also wasn't asked for in the challenge) where you are doing the calculation. This calculation should actually be done right in the interpolated string.

  2. You are using puts on the interpolated string when the challenge is asking for a return.

  3. Challenges are very picky and very strict. So, this one is more just that. You are missing a period inside of the String Interpolation.

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

Keep Coding! :)

The method should return that string so try return instead of puts:

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