can someone explain why explicit conversion is needed?
there is a + operator defined in the byte struct, why is it not used in a + b?

i guess byte are implicitly converted to ints, but how to use the byte + operator then?

I'm glad that I can actually change the type of thing that gets returned in this debug instead of having to deal with working with byte, which I don't even know how to use. :((((((

Spelling mistake: forgot an "a" before "simple program"

If you study mathematics or like math in general, the math related katas are fun.
If you are searching for a job or you are about to take a test, you are more stressed to learn and you're interested in the "useful" ones, so math related katas can be annoying in that case.
I had similar issues in the past. The thing that helped me was filtering katas, on the left part of the screen, select the appropriate tags.

Python translation added, please review.

P.S. I'm not extremely sure about this one, as bytes don't work the same way they do in Java, so I replaced them with strings instead. Hope it doesn't change anything, the whole idea is still the same. Feel free to reject the translation if it's not okay. :)

Yeah you are right, that's my bad I apologize. Honestly I was just frustrated because I have a class on SQL coming up so I'm trying to learn it, and I go to do one of these challenges, and find the sql function or w/e that seems like it would do the job, and I plug it in using the same syntax I see on w3schools or wherever I found the info, and the interpreter on here will tell me it doesn't recognize the function or something. That's what I had been doing before this challenge. I wish there was a setting that would not allow me to type anything if my blood pressure rises above a certain level, maybe I should look into that. Clearly there is something I am still doing wrong with the SQL, but it is frustrating. Anyway, just wanted to say that since I'm not able to just delete my comment...

Programming is a very wide field. Yes, you can do alot of programming without much math knowledge, but that is only because you are using a lot of libraries that do the math for you. Somebody has to write all these libraries and they need to know all this "useless math crap". So, please don't be ignorant and recognize the actual usefullness of these katas.
If you don't want to dive into this sort of programming just skip those katas.

Finally, I actually learned something related to programming from doing one of these challenges. The past 10 or 20 have all just been useless math crap I'll never have to know again unless I decide to do more of these challenges. Thanks to creator of this for actually helping me learn something related to Java.

Why so poorly rated? This is something that should be learned for c# in case you run into it later.

I love this little cute kata! Thank you!))

Hey! Here's a good explanation: https://stackoverflow.com/questions/18483470/is-addition-of-byte-converts-to-int-because-of-java-language-rules-or-because-of
