Do numbers go on forever

Answer 1

The question is a bit vague. The set of all natural numbers N (0,1,2,...) has no 'end', there is no 'largest number', in other words: it has an infinite amount of elements.

The set of all real numbers R (which includes -2,sqrt(3), pi, e, 56/8, etc.) als has infinitely many elements, but there is a difference between the two:

N is a countable set (you can 'count' all the elements), but R is not. If you want to know more about this, you should search after terms like cardinality, countable set, aleph, ...
