## What are numbers?

In this forum, questions are asked which are really tough to answer. Some philosophical, some regarding morality and many others. Have fun, and post your own personal tough questions!

## What are numbers?

Natural, integral, rational, real, complex, hyper natural, hyper integral, hyper rational, hyper real, hyper complex, surreal, ordinal, cardinal....

Numbers abound.

And why is .999repeating = 1?

I think we rode this merry-go-ground before! Rules of rounding prevails, defining what is practical or the application. .999=1 The fraction trick, and converting to decimals. What shell is the pea under!

## Re: What are numbers?

The following two sequences are Cauchy equivalent:
{.9, .99, .999, .9999, .99999, .999999, etc.} and
{1, 1, 1, 1, 1, 1, etc.}

Meaning that .999repeating=1.

Let's start somewhere specifically
what is a real number? Did mankind create real numbers?

Its all beyond me! As long as my check book is a positive number, its real for me. Maybe your pal will come back and debate this to lunatic levels. You, kanster, and Dissintary or what ever his name is.

http://en.wikipedia.org/wiki/God_Created_the_Integers

God Created the Integers: The Mathematical Breakthroughs That Changed History is an anthology, edited by Stephen Hawking, of "excerpts from thirty-one of the most important works in the history of mathematics." The title of the book is a reference to a quotation attributed to mathematician Leopold Kronecker, who once wrote that "God made the integers; all else is the work of man."

Quantification is both objective and subjective.
