parthkohli · Answer

Axiom: number + number = another number

Axiom 2: 4 is a number

hba · Answer

Well ^^ You Are wrong,thats not an empty set,it has one object :)

anonymous · Answer

Correct

hba · Answer

{ } < Empty set

anonymous · Answer

So is it 1?

hba · Answer

Well Its Not The Number 1 but it is 1 object :)

anonymous · Answer

That is (a) set theory definition of 1.

anonymous · Answer

Why is it worse than "1"

hba · Answer

Well I Agree With You On That Note

anonymous · Answer

Why do we need a set theory definition of 1 at all?

hba · Answer

Well Thats Not Exactly What Is Being Asked Here :)

anonymous · Answer

To answer what is being asked, you have to define "number"

hba · Answer

But It Is Not Necessary We Talk About It With Respect To Sets :)

anonymous · Answer

Define it however u like, I gave one (mathematical) definition.

Do you have another definition?

unklerhaukus · Answer

one is an egg

anonymous · Answer

"I"  (as in individual)

hba · Answer

^ dis agree ,One is One

anonymous · Answer

So your proof goes, One is One, so One is a number..?

hba · Answer

Exactly :)

anonymous · Answer

1 is a symbol representing a number.....(maybe)

hba · Answer

Maybe^^

ganeshie8 · Answer

1 is a symbol representing repetititiveness

anonymous · Answer

lol

maheshmeghwal9 · Answer

1 is a first natural number.

anonymous · Answer

No number is less than 1...?

anonymous · Answer

No natural number is less than 1...

hba · Answer

Because 0 things cannot exist in nature :D @maheshmeghwal9

anonymous · Answer

Ah, the physicists viewpoing...:-)

anonymous · Answer

viewpoint*

maheshmeghwal9 · Answer

but @estudier that no number is less than 1 but 0 is a whole number.

anonymous · Answer

What's a whole number?

maheshmeghwal9 · Answer

said*

hba · Answer

With Respect to sets W= {0,1,2,3.....}

anonymous · Answer

http://en.wikipedia.org/wiki/Whole_number Pick one...

maheshmeghwal9 · Answer

{0,1......$\infty$}

anonymous · Answer

A set containing infinity as a member.....

maheshmeghwal9 · Answer

@estudier

maheshmeghwal9 · Answer

a set starting from 0 to infinity

anonymous · Answer

Do u mean an infinite set?

maheshmeghwal9 · Answer

yes !

anonymous · Answer

OK, which one?

maheshmeghwal9 · Answer

which is starting from 0.

hba · Answer

@estudier Stop Playing and get to the point :)

anonymous · Answer

Natural numbers including 0

anonymous · Answer

Seems we are talking about sets after all....

maheshmeghwal9 · Answer

hmm ...

u r confusing me @estudier

hba · Answer

Well Natural number does not include 0

anonymous · Answer

They do or don't u have to say which.....

anonymous · Answer

Or u can say  "positve" or "non-negative" integers....

hba · Answer

We Can Say Non-Zero Also :)

anonymous · Answer

As you like, it just has to be clear...

anonymous · Answer

So, according to set theory, 1 is not a number.

It is a representation of the set containing the empty set.

hba · Answer

Would You Like To Provide Example :)

anonymous · Answer

And we can define all the other "numbers" by (transfinite) induction

hba · Answer

@estudier Can You Define A Set ?

anonymous · Answer

Like point and plane...

anonymous · Answer

Something has to be primitive else you are going in a circle.....

hba · Answer

Well You Have To Go In A Circle Before You Come To A Certain Point :)

anonymous · Answer

Good place to finish:-)
