Notice there is only 1 full headline (from /r/NoStupidQuestions) visible, it doesn’t even show the full post. There are 3 of those “trending” boxes but only 2 of those even fit their headlines because they are like 3 words long, they cut off anything longer including the description
I originally became addicted to Reddit because of how streamlined it was to skim dozens of headlines and pick from lots of content, seems they have decided content is not something they want to provide anymore :/
Okay, so does anyone wanna talk about the math thingy in the post?
They jump from 0.99999… = 1 to 0.99999… = 1 - 1 in the step where they introduce the limit, because the value of the limit they wrote is 1, not the 0 they probably thought it was. So the whole thing is a crapshoot from the start - functionally no different from setting up 1 = 1 - 1, simplifying to 1 = 0, and claiming you broke math
If it started: 0.999… = 1 - lim(1/n) then maybe we can talk, but I have no idea where 0.999… = 1 - lim(1 - 1/n) comes from, that’s just incorrect
According to math 0.999=1??? Who is this guy’s math dealer?
That part’s real - not for 0.999 but for 0.999… (repeating). The classic proof goes:
Let x = 0.999999…
Then multiply both sides by 10. You now have:
10x = 9.999999…
Now subtract the first equation from the second equation. You get:
10x - x = 9.999999… - 0.999999…
9x = 9
Then divide by 9 to complete the proof:
x = 1
That’s a neat little proof, TIL.
Also 1/3 is 0.333 recurring.
So 1/3 x 3 is 0.999 recurring. But 1/3 x 3 is also 1.
No, not TIL, you’re supposed to say QED 😋 just kidding
You can’t find another number that fits between those 2 numbers… therefore they are the same.
Not really
