Real number: Difference between revisions

Revision as of 23:20, 28 April 2022

Calculus is based in the system of real numbers and their properties.

Real numbers are classified as rational numbers (denoted by Q), integers (Z), whole numbers (W), natural numbers, and irrational numbers. In order of inclusion, non-irrational real numbers can be ordered as follows:

$N\subseteq W\subseteq Z\subseteq Q$

a.(b+c)=a.b+a.c

a+b=b+a

a.(b.c)=(a.b).c

a+0=a

a.1=a

a.1 =a

a+(-a)=0

a.(1/a)=1 where a is not 0
