While I see you have 68 videos on YouTube, how many lessons exist so far in your Ruby series? Are all 68 Ruby related or is that total videos on all subject matter?

I don’t understand the modulo can you please help me when you said 17 % 4 you said the remainder is 1 but when I devided 17 with 4 I got 4.25 so how is the remainder 1? I did see if I devide it with 4 again I get 1.0625 where the remainder is 1 is that how you got it?
