Question

Method Returns on Ruby basics course, I cannot for the life of me work out where I am going wrong!

Question is:

Use string interpolation to return the remainder inside the sentence “The remainder of a divided by b is c.” where a is your “a” variable, b is your “b” variable, and c is the value of a % b.

and i get met with

"" Bummer! NameError: undefined local variable or method `a' for main:Object""

Please help!

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

end
mod (a%b)

Hey Oliver,

You're more or less on the right track, but there a couple of issues.

First, you are using puts when the challenge specifically asks you to return the string.
Second, You are interpolating the variable c, but you haven't declared it anywhere. This code would work and pass the challenge if you changed return a % b to c = a % b. (And the puts to a return).

But an even DRYer approach would be to do the actual calculation right in the interpolation.

Below is the code I would use. Have a look, and I hope it makes sense.

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

Keep Coding! :)
