Embed return value method in string

Hello,

Sorry I got stuck with methods. Could you please check the code I put.

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

You're using the value of c before declaring it.

Per the challenge, you don't need to return c, just the string that contains the formatted sentence.

The return statement should also come before c, and not be part of the assignment. See the working code below

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

But to use a more ruby-esque style, we can just do the arithmetic in the string interpolation, and omit the return statement. Ruby will by default return what ever the last statement of a function evaluates to. 

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

Thanks Samuel!

I used the second one however without the spaces between characters, probably the translator was not perfect, I'll check it again.
