This sentence is false, because it happens to have just one exception: when x=0, x*y=0 for all real numbers y and there is no way to get some y so that 0*y=1. For all non-zero real numbers x, there is a real number y such that x*y=1. This sentence is true, because for non-zero x ...Short description: Mathematical function returning -1, 0 or 1. Signum function y = \sgn x. In mathematics, the sign function or signum function (from signum, Latin for "sign") is a function that returns the sign of a real number. In mathematical notation the sign function is often represented as \sgn ( x). [1]And then we have that, for the real numbers between $0$ and $1$, that the set of real numbers is simply the set of all subsets of natural numbers. Each subset corresponds to some real number between $0$ and $1$. And in this way, all real numbers can be considered to be some set based only on nested sets of the empty set.The set of rational numbers is denoted by the symbol R.
