    2/0 and 1/0 are not defined (because infinity is not a number)

    Wikipedia says : it can be often referred to as number but it is not exactly a number like real numbers.

    I always do, I wonder is there anything real in this world? Or all are just imaginary.. Do 1 exist ? Do 2 exist? :)

    What mathematics does (in the usual model) is to posit (stipulate) the existence of an infinite set (the natural numbers). Then all the other infinite sets used by mathematics follow on from that axiom.

    No, infinity is not a number. And 1/0 is not infinity.
