5 * infinity does equal 20 * infinity... but the 20 * infinity is a BIGGER infinity... if you can comprehend that. ;p
Edit: I changed it to * just so it is easier to comprehend, works the same with division.

5 * infinity = infinity
20 * infinity = infinity

Neither is "bigger" or "smaller" than the other.

People reject the notion on the basis of their intuition, but intuition is of no help here, because nothing in the physical universe reflects infinity. It's a matter of math, limits.

It doesn't, because it's not written 1. It's "1-dx", "the smallest possible value less than one", so close to 1 that it's the same even within our mathematical definition, but it's just a bit less.


Why would it be dx? There is no dx whatsoever Statiqhock...

x = .999...

10x = 9.999...

10x = 9 + x

9x = 9

x = 1

Does that help you understand? It is definitively 1, stop trying to act like you can conceptually misconstrue definitions; we simply don't need to in this case.

Here's the thing: There's a difference between theoretical mathematics and actually applying it to the real world.

.999 repeating is so close to 1 that it may as well be 1, but there's no real world example where something is that incredibly close to 1. Looking down to the atoms, there can only be whole number atoms, right?

Another person joins the "0.999... is a finite number" club.

the easiest interpretation is 1/3 = .333 repeating

3/3=1 =.999 repeating

Why are Reds commenting on this while it's still in GD yet has NOTHING to do with League?

That's fine. I am human. I am allowed to be incorrect.


You should talk to Damiya about getting that fixed.

That's the key to people's mental block on this: Incredibly close to 1 is not the same thing as infinitely close to 1. What do you think the mathematical definition of infinitely close to 1 is in calculus? Yeah. Get it yet?

It's like playing chess and arguing over how horses don't move like knights in real life.

Yes because screw prime numbers... (sorry i just despise there non-evenly devidedness with a passion...)
