This is the last question for completing the course but I'm stumped on where to go. I tried to follow the same format of the previous video. What am I doing wrong and how do I solve it?
def mod(a, b)
puts "The remaineder of #{a} divided by #{b} is #{c}."
return c=a%b
end
puts mod(2,9)

Per the challenge, don't print the string to the console. Just return it.
def mod(a, b)
c = a % b
return "the remainder of #{a} divided by #{b} is #{c}"
end
Using code that's more "ruby-esque", you can just use the arithmetic in the string interpolation, and return without the return statement, like so:
def mod(a, b)
"The remainder of #{a} divided by #{b} is #{a%b}."
end
