This code seems to output what the exercise is looking for. Am I calling the method wrong? I don't quite understand what I'm doing wrong in this exercise. Thanks!

method.rb
```def mod(a,b)
a % b
end

a = 100
b = 10
c = mod(a,b)

puts "The remainder of #{a} divided by #{b} is #{c}."
``` PS I'm not sure if this links to the instructions or not. Just in case it doesn't, here they are:

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.

Here is the correct code:

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

a = 100
b = 10
c = mod(a,b)
```

Take a look a see if you can understand how it works. cheers. `return` the string, "The remainder of `#{a}` divided by `#{b}` is `#{a % b}`." in `mod()`.
