Here's the question you clicked on:

What is the difference between the terms denumerable and enumerable.
What's the meaning of them?
a set is "denumarable" if you can count the elements first, second, third etc
just like when you first learn math as a 4 year old by learning to count things. denumerable means "countable"
A denumerable set is a so-called countable set, an an enumerable set is something that seems to be used in computer science, but is essentially the same thing.
and counting things means you are assigning a positive integer to each item first item, second item, third item, etc so it is actually pretty sophisticated. you are creating a one to one function from the positive integers to the elements of the set
so to be very formal, you can say a set S is "denumerable" "countable" etc if there is an injective function (one to one function) from \[S \to \mathbb N\]
what are you talking about @robot1234
think maybe robot is bored
Might be a clever method of squeezing a medal from someone who thinks robot1234 is helping
I have seen these earlier, users coming in and just posting a nonsense and expecting to get a medal.
This is a good trick after all
Driveling for medals lol!
