∞ + 1 = ∞

The above must be wrong, because the ∞ in red obviously wasn't ∞. Therefore it follows that the answer ∞ has to be wrong.

∞ + ∞ = ∞

Again, the above must be wrong, for the same reasons as above.

∞ - ∞ = 0 (or possibly ∞)

?

I'm totally flummoxed here.

We live in one infinite universe. There can only be one universe, since it is infinite and there can surely only be room for one in infinity.

So, could it be that :

∞ = 1?

What do you think?
