what happens when my rating hits zero?

No!Don't!

If it goes backwards 1 rating point then the rating will be 9999999999 repeating cuz 99999999999 repeating + 1 = 0 because the carrying of the 0 never stops then it goes like 000000000 forever. 0-1=-1 so -1=999999999999 repeating

actually 99999999999+1=1000000000000 NOT 0 .

ok then. rate higher than hikaru by losing games on purpose? no thank you.

If your rating is less than 0 then you will get a negative rating

I already said that, I'm afraid.

I don’t think you can go below 100 right

No, 100 is the lowest you can go.

Wait I’m gonna try

A black hole is formed and all the pieces fall into it.

No 100 is the limit

You can’t get lower

But you can get higher

And you should

your chessboard turns to ohio

if you lose a game integer underflow will happen and you will be the strongest elo alive
