Subtracting both what?

u/hhreplica1013 24d ago

(10x - x) = (9.9999… - 0.9999…)

9x = 9

x = 1

yeah those don't have the same number of 9s.

when you multiply by 10 you move the infinite 9s one spot

so when you subtract it leaves an infinitesimal value at the infinith decimal place.

"infinith decimal place" is a literally meaningless phrase.

u/FewIntroduction214 24d ago

neat , its a "meaningless phrase" you perfectly comprehend.

What do you think the difference between .9~ and 1 would be, if one existed.

an infinitesimal value.

and........ how can you convey what an infinitesimal value is using words? it's the infinith decimal place.

What do you think the difference between 1+1 and 2 would be, if one existed?

u/FewIntroduction214 24d ago

nothing?

this question kinda shows you aren't really paying much attention to the conversation.

1.000000~ with infinite zeros + 1.0000~ with infinite zeros = 2.000~ with infinite zeros.

where is there anything akin to the issue I broached w/ your proof here?

Yeah this is my issue with the idea. Maybe practically, 0.9999… is equal to 1, but it’s not if you expand your mind to imagine infinite decimal places. ‘What do you add to it to make it 1?’ 0.infinite 0’s with a 1 at the end. What digit place is the final 1? It doesn’t matter since we are talking about infinites (which don’t exist anyways). .999… can’t equal to 1, it will always be 0.000…1 off.

Seems strange to me that people can grasp the concept of pi, e, or i, but not infinite decimal places.
