This code works in Workspaces. Any idea what the error means. For convenience, I've copy and pasted the question and error message below: "In the previous challenge, we wrote a method that returned the remainder of two arguments when divided. That's cool, but it would be nicer if the method returned the remainder in a nice full sentence. 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. Bummer! Something doesn't look quite right. Double check your spelling & punctuation"
def mod(a, b)
puts "Dividing #{a} and #{b}"
puts a / b
return "The remainder of #{a} divided by #{b} is #{a % b}"
end
mod(4, 2)

65,469 PointsThere are a couple issues:
- You are explicitly calling the function. The code challenge never asked you to call the function, it only asked to
define
the function. - You are printing two messages that the challenge never asked you to print.
- This is very minor, but even if you fix the above it won't pass because you are missing an extra period at the end of the string your
return
ing.
i hope this helps
Happy coding!

2,237 PointsThanks. It was the period?. What's the difference between calling a function and defining a function?

65,469 PointsDefining
a function is kind of like assigning a variable to a value, expect you are "assigning a block of code to a name".
Calling
a function is kind of like accessing the value of the variable, except you are executing (running the code inside) the function.
