This method seems to return the correct answer but It's not accepted by the exercise.
Can anyone demonstrate what exactly I am missing from the below code that would allow me to complete the exercise?
def mod(a, b)
return puts "The remainder of #{a} divided by #{b} is #{a % b}"
end
mod(5, 2)

Treehouse TeacherTwo things here. And one is a tiny boo-boo! First, you may return the string or puts the string... not both. Secondly, the challenge requires a period at the end of the string or it won't pass. Take a look at my return line (Note: this is your code after I remove the puts and add a period)
return "The remainder of #{a} divided by #{b} is #{a % b}."

Again, to clarify, because I know this can be confusing if you're just starting out: return simply returns the value, puts prints it. Furthermore, the return keyword is actually optional in Ruby, although in complex methods it is preferred for clarity (and of course, if you have multiple points of returns, it is necessary).

def mod(a, b)
c = a % b
end
Next, there is no need to use the puts method, like what Jennifer Nordell and *Jacob Bergdahl * said. So the final step is
def mod(a, b)
c = a % b
return "The remainder of #{a} divided by #{b} is #{c}."
end
Don't forget the period at the end of the string!
Oh yeah and one last problem: Don't call the function. The quiz will run it and test it for you. That means don't write this:
mod(5, 2)
Hope it helps! ~xela888

Treehouse TeacherIt's interesting to note, xela888 that according to the instructions you need the variable c to hold the value. The challenge passes without it :) Mostly challenges are very picky, and would require this. For whatever reason, this particular challenge lets you skip that part.

7,812 PointsThank you all for your help on this one. It all helped to show me where I was going wrong and more importantly, to help me understand it a little better.

Treehouse TeacherSorry, I don't know why it's not putting the quotes in the markdown. This has happened to me twice in the past two days.
