Depending on who you believe, it's a set (and so is everything else)

Guys, a simple but mathematical explanation

Natural numbers are the numbers which we normally use for counting, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Ok. a number is a measure of quantity

estudier Group TitleBest ResponseYou've already chosen the best response.0
"Ok. a number is a measure of quantity" So 2 is a measure of 2?

Thabo Group TitleBest ResponseYou've already chosen the best response.0
Yes, a "simple" as that

estudier Group TitleBest ResponseYou've already chosen the best response.0
That isn't simple, it is circular and doesn't mean anything...

How is my definition wrong
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
It is the same as saying 2=2 which is not wrong, just devoid of meaning.

estudier Group TitleBest ResponseYou've already chosen the best response.0
That's an improvement....what is "arithmetical"?
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
Now you have gone all circular as well...:)

Thabo Group TitleBest ResponseYou've already chosen the best response.0
Give us your definition then
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
I already said, if you don't want to take the "naturals" as given, then you canuse a set theoretical construction of number, starting withy the empty set.

Thabo Group TitleBest ResponseYou've already chosen the best response.0
I don't understand you
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
Assuming you want a "mathematical" definition of number, then you need to find a way to use set theory to do it because that is the currently accepted foundation for mathematics.

Thabo Group TitleBest ResponseYou've already chosen the best response.0
I just wanted to know what is a number according to you guys that all
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
Mathematically, it is a set.

"properties of the natural and real numbers can be derived within set theory, as each number system can be identified with a set of equivalence classes under a suitable equivalence relation whose field is some infinite set" http://en.wikipedia.org/wiki/Set_theory#Axiomatic_set_theory

Thabo Group TitleBest ResponseYou've already chosen the best response.0
oh, that a pretty interesting definition. Thanks
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.0
Normally, for day to day mathematics, you don't really need this. Another way is just to take the naturals (beginning with 0 or 1 according to taste) as being somehow "God given" and then get everything else from those.

Thabo Group TitleBest ResponseYou've already chosen the best response.0
Ok. thanks everyone!

SmoothMath Group TitleBest ResponseYou've already chosen the best response.0
This is really almost an epistemology question more than a mathematical one. Mathematics solves problems based on the foreknowledge of numbers and counting. At least for the common man, knowledge of numbers is axiomatic, it is understood knowledge that other knowledge can be derived from.

an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations and for showing order in a series or for identification

A number is a measurement without units

Thabo Group TitleBest ResponseYou've already chosen the best response.0
Oh, not what do you mean?
 2 years ago

UnkleRhaukus Group TitleBest ResponseYou've already chosen the best response.0
Numbers come from measurements, i.e. from the comparison of a selection of reality with a scale or rule, where the selection is best represented on the scale, is designated a number, to distinguish it from another place on the scale

Thabo Group TitleBest ResponseYou've already chosen the best response.0
Yes, I like that word "comparison"

would numbers mean anything at all if well didn't use the same scales?

A number shows the amount of something and was created to show how much something was.

JoJoPhoenix Group TitleBest ResponseYou've already chosen the best response.0
For instance, many thousand years ago people had animals, and then they suddenly wanted to count them, so they created the first numbers, just some line that show the amount

There would be trouble in this world without "comparison"

The truth is, numbers, just like words, are defined arbitrarily, but are useful for human communication of ideas that are inherent in reality.

truth is a binary measurement , requiring a measurer , such as a person

0=False 1=True, are these arbitrary, @SmoothMath
