WTF are you talking about???

x = 0.9999...
10x = 9.9999...
10x - x = 9.9999... - 0.9999...
9x = 9
x = 1.

that is exactly what you wrote
you just said yourself that 9*0.999... would be 8.999...

the reason you did the statement was to show how you make it = 1 but if the math is done properly you prove that 0.999... = 0.999... and that's it.

No it doesn't in a proof you have to get the next step from the previous, I am not multiplying 9*0.999... anywhere in the proof, I am subtracting 10x - x.

Subtract the line above that, and tell me what you get.

I am not stupid, i know how to subtract. but what does the part i highlighted in red mean. last time i checked when you put a letter next to a number it means times and you put the part 9x there so it means 9 times x which is what was said.

as far as the calculus thing, I don't feel like looking into it at the moment but what it looks like (from what i understand) is just more number shuffling to try to prove the point that still makes no sense from the original number shuffling you did with the statement of
x = 0.9999...
10x = 9.9999...
10x - x = 9.9999... - 0.9999...
9x = 9
x = 1.
