[1amayzingman] replied to a poll 1 ÷ ∞ = 0 in Discussion Hall

It can't have any inverse, as long as we assume a*∞=∞ (which only makes sense). Here's why: Let's say it has an inverse, we'll call it c. Now...

[1amayzingman] replied to a poll 1 ÷ ∞ = 0 in Discussion Hall

It makes sense, up to a point, but infinity can't have ANY inverse at all, much less 0. Otherwise, the set of numbers under multiplication no longer...

[1amayzingman] replied to a poll 1 ÷ ∞ = 0 in Discussion Hall

1÷∞ can't equal 0 if you want infinity to be part of a group, because it implies that 0*∞=1. So let's see if 2*(0*∞)=(2*0)*∞. The right hand side...

Yeah, it's actually not possible to have a group with ∞ if a+∞=∞. I proved it above using maths. It's still fun to think about these sorts of...

Okay, I think this is actually impossible if we want a group (which we do). First, the definition of a group: A group is a set together with an...

/∞ only has meaning if infinity has an inverse. Which, it doesn't necessarily need. For example, 2 doesn't have an inverse mod 6. There isn't a...

Yeah, the cancellation law wouldn't apply to infinity, because if it did then you would get a=b for a=/=b, as demonstrated above. You can't expect...

No, you assumed that a + inf - inf = a, which is clearly not the case by definition. a + inf - inf = a + inf still.

After thinking about it, you could amend the set of real numbers to include infinity by giving it the following properties: a+∞=∞ for any a b*∞=∞...
