x=-i is the unary minus operator which negates the value right of it. It doesn’t matter if that value is a literal (-3), a variable (-i) or a function (-f()).
x-=i is short for x = x-i, and here it’s a binary subtraction, so x is set to the result of i subtracted from x.
There’s a couple people in this threat who seem to actually think that x = -i is some weird magic instead of a standard feature that’s present in every major programming language.
Nope, it is not.
while
x = 5 i = 2 x = -i // x => -2x=-iis the unary minus operator which negates the value right of it.

/sto my future silly replies I think… that said, I’ll never pooh-pooh a well thought response, so thanks for the nice write-up!Thanks, I totally missed your sarcasm :)
