Best ResponseYou've already chosen the best response.0Natural numbers are the numbers which we normally use for counting, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

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

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

Best ResponseYou've already chosen the best response.0How is my definition wrong

estudier

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

Best ResponseYou've already chosen the best response.0That's an improvement....what is "arithmetical"?

estudier

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

Best ResponseYou've already chosen the best response.0Give us your definition then

estudier

Best ResponseYou've already chosen the best response.0I 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.

estudier

Best ResponseYou've already chosen the best response.0Assuming 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.

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

Best ResponseYou've already chosen the best response.0"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

Best ResponseYou've already chosen the best response.0oh, that a pretty interesting definition. Thanks

Best ResponseYou've already chosen the best response.0Normally, 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.

Best ResponseYou've already chosen the best response.0This 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.

Best ResponseYou've already chosen the best response.0an 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

Best ResponseYou've already chosen the best response.0Oh, not what do you mean?

UnkleRhaukus

Best ResponseYou've already chosen the best response.0Numbers 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

Best ResponseYou've already chosen the best response.0would numbers mean anything at all if well didn't use the same scales?

Best ResponseYou've already chosen the best response.0A number shows the amount of something and was created to show how much something was.

JoJoPhoenix

Best ResponseYou've already chosen the best response.0For 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

Best ResponseYou've already chosen the best response.0The truth is, numbers, just like words, are defined arbitrarily, but are useful for human communication of ideas that are inherent in reality.

UnkleRhaukus

Best ResponseYou've already chosen the best response.0truth is a binary measurement , requiring a measurer , such as a person
