This is all too complicated for me.
What's your favourite paradox?

That's not the computation franku is doing however. Hence, he is indeed fully correct. Regards,

If you subtract 0.999 recurring from 9.999 recurring you are left with 9, hence my calculation. edit: the recurring decimal values cancel themselves out

That'd still make your calculations wrong
You can put any amount of 9's after the .... and it'd still follow the same principle that I wrote

Right, here's a more visual representation of what he has done:
The last line shows 3 different ways of expressing the exact same number: 0.999..., 9/9 and 1. Another way of expressing 0.999... or 0.9 recurring is by the following infinite (and converging sum), which is equal to 1: The above notation effectively means: 0.9+0.09+0.009+... going on forever. I'll show you that the above sum is true as it is a geometric series, so the sum to infinity is: where a is the first term (in this case 0.9) and r is the common ratio (what we multiply to get the next term) which is 0.1 in this case. When we apply the formula: Hopefully this clears it up a bit more. Regards,
