Infinity has different meanings in different contexts. Here are some of them:

In set theory, it means a set that has an infinite (more than any finite) number of elements. For example, the sets of integers, and the set of rational numbers, are countably finite (aleph-zero), while the set of real numbers is uncountably finite (aleph-one in this case).

In calculus, it is used to indicate that something can grow without bounds - more than any specific number. For example, 1/x is not defined, in calculus, for x = 0, but if x gets closer and closer to zero, the division produces larger and larger number - larger than any number you specify. It is said, in this case, that 1/x tends towards infinity, when x tends towards zero.

What is the meaning of Real in math?

Real numbers are numbers that exist from negative infinity to positive infinity and everything in between. real numbers consist of every number you are used to. Imaginary numbers are numbers that aren't used in conventional math (such as i)

Infinity is not a defined number. It describes, in math, the endlessness of numbers.


Why is infinity such a dreadful place?

'Infinity' is just a concept of something that is without limit. You find infinity used in math (numbers) and physics (distance or a measurement like time), a lot. Infinity is not a 'place', so cannot be dreadful.

What is infinity add infinity add infinity add infinity?

As Infinity means to be without end, adding infinity to infinity to infinity would not change that. Adding infinity to an infinity would be Infinity itself. However, this could change if other mathematical processes are done. ================================== When real math people run into the thing we call "infinity", they call it "undefined". It's not a number, and it doesn't participate in the operations of arithmetic like numbers do. So technically, this question describes a process that doesn't exist in math. A lot like asking "What is cow add stick add temperature add democracy ?"
