2,355 PointsNot sure what I'm doing wrong...
I'm not sure what exactly I'm doing wring, but it's probably to do with the end of my string...any suggestions?
def mod(a, b)
puts "The remainder of #{a} divided by #{b} is 'a % b'"
return a % b
end

You're on the right track, but there are a couple of things:
You'll need to do the calculation for
a % bbefore the string and store it in a variable calledc.The challenge is asking you to
returnthe string, but you are usingputs.There is no purpose of the last return statement.
Below is the correct code for your reference. Have a look, and I hope it'll make sense.
def mod(a, b)
c = a % b
return "The remainder of #{a} divided by #{b} is #{c}."
end

You want to make sure to actually run the calculation between a and b. Try something like this:
def mod(a, b)
"The remainder of #{a} divided by #{b} is #{a % b}."
end
One of the benefits of Ruby is that the last line by default will be returned so you don't have to specify a return value.

Guess you type a bit faster. Lol. But, you're missing the period... and we all know how picky the challenges are.

28,888 PointsYou're right Jason, I've made that slight modification to make sure to remove any chance for error. Thanks for that catch.

2,355 PointsThis is the question: 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.
