Then don't do katas that have Math in the title. I don't know why you say it's not code either: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math

can't agree more

Blasphemer.

But i don't think using the loop would be the right way.

Not really. You can use loops if you want. The math here is just for shortcuts..

elaborate?

Agreed. Every task related to 99 bottles of beer should be removed from any programming textbook, along with Dice, Pocker and Tic-Tac-Toe.

Then I'm glad you're not forced to solve these kata's. Let me introduce you to the "skip" button ;-)

Agreed, I'm sick and tired of all these math problems.

Could you elaborate why?

Agree

Yeah, I was having a hard time understanding it too. I then updated the description, let me know if it's easier to understand.

It has precisely all the information necessary to understand both domain and codomain, as well as the specifics of the result. It is precisely because it is accurate that it is so verbose, or, as you may see it, convoluted.
Putting it in terms designed for the lowest common denominator (e.g. "You need to compare both strings to find the biggest difference") lacks huge amounts of detail needed to describe the task in its entirety. What strings? What does "both" mean. Difference of what? etc. And then you get thousands of issues raised in the discourse from users who thhought they knew what they needed to do, but failed the tests none the less.

Natan, this isn't about perspective, it's about clarity. It lacks information.

hahahah ur maths kid
