The set of the p-adic numbers contains the rational numbers, but is just not contained in the complicated numbers.
Superreal and surreal numbers prolong the real numbers by including infinitesimally little numbers and infinitely huge numbers, but nevertheless sort fields.
Irrational Numbers: The selection that can't be expressed because the ratio of 1 above another is named irrational numbers and it is represented because of the image ”P”.
Irrational Numbers arrived into existence as a result of geometry, as Pythagoras found out a very elegant Resolution for any proper-angled triangle referred to as the Pythagoras Theorem.
