what is real numbers???????​

Answer 1

$\huge { \underline{ \underline \pink{answer}}}$

In mathematics, a real number is a value that represents a quantity along a continuum, such as -5 (an integer), 4/3 (a rational number that is not an integer), 8.6 (a rational number given by a finite decimal representation), √2 (the square root of two, an algebraic number that is not rational) and π (3.1415926535..., a transcendental number). Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced. Any real number can be determined by a possibly infinite decimal representation (such as that of π above), where each consecutive digit ar at rank r indicates the addition of ar 10-r to the decimal truncated at rank r-1. The real line can be thought of as a part of the complex plane, and correspondingly, complex numbers include real numbers as a special case.

Answer 2

Answer:

A real number is any positive or negative number. This includes all integers and all rational and irrational numbers. ... For example, a program may limit all real numbers to a fixed number of decimal places
