What is ∞ + ∞ = ????

[Edwardo Piet]

Interesting.

I don't know much about the countable/uncountable things... but am I correct that a countable infinite set is an infinite set of finite numbers or something like that?

I didn't understand the part about math. Lol.

Sets don't always contain numbers.  For example, the elements of a power set are sets. To clarify, the infinite set of all positive integers is an element in the power set of the set of all positive integers. Thus, in this instance, we have an infinite element in an infinite set.

Is a countable set more finite than an uncountable set?

What confuses me, is the uncountability of something kind of suggests infinity to me. If you have a truly infinite number of something . . . how can you count it?

I'm guessing they're just math terms. I suck at math.
