Hi,

I have nowhere near the level of understanding that you guys have but I have a question that just won't go away. When looking below:

oo- -9 -7 -5 -3 -1 0 +1 +3 +5 +7 +9 +oo

They are the two number lines and each of them extends to infinity in both their relevant directions, (with all that comes with infinity).

Is there any concept in mathematics that joins the two infinities together? Any concept that gives the two continually extending lines, which would beintentionallymade to meet, a useful purpose?

Something that shows a new relationship between positive and negative numbers?

If so, could a new kind of maths be built on this concept and would it have any worth?

I'd be happy for your thoughts,

All the best,

Ste.
