thank you very much i understand now.

The index starts at 0. I used the modulo % to add 2 to the power of 0. This = 2 and also = Even.
no need for anything else as the remander and only have aone result. That is = 1 and is Odd.

I suck at explaining and doing math so my appoligies in advanced for the crude explanation. However that is how I got passed this Kata.
I also tried to explain without giving the whole thing away.

It's not 2 == 0, there is something else before it. You should try following some tutorial to get familiar with fundamentals of the language before solving katas.

i will leave this here: the "" is where you write your code not some 'string' thing, i got very confused tbh.
