WebSep 5, 2024 · The extrended real number system consists of the real field R and the two symbols ∞ and − ∞. We preserve the original order in R and define − ∞ < x < ∞ for every x ∈ R The extended real number system does not form an ordered field but it is customary to make the following conventions: If x is a real number then x + ∞ = ∞, x + ( − ∞) = − ∞ WebNumbers should be distinguished from numerals, the symbols used to represent numbers.The Egyptians invented the first ciphered numeral system, and the Greeks followed by mapping their counting numbers onto Ionian and Doric alphabets.

Web1. That there is a rational between any two irrationals comes from the definition of the real number system;the reals can be extended to larger ordered fields that have "infinitesimals", members that are positive but less than any positive rational.If x is one of these "infinitesimals" then there is no rational between x/2 and x, but x is not ...
