In mathematics, the natural numbers are those used for counting (as in "there are six coins on the table") and ordering (as in "this is the third largest city in the country"). In common language, words used for counting are "cardinal numbers" and words used for ordering are "ordinal numbers".
Some authors begin the natural numbers with 0, corresponding to the non-negative integers 0, 1, 2, 3, …, whereas others start with 1, corresponding to the positive integers 1, 2, 3, …. Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the whole numbers, but in other writings, that term is used instead for the integers (including negative integers).
The natural numbers are the basis from which many other number sets may be built by extension: the integers, by including an additive inverse (-n) for each natural number n (and zero, if it is not there already, as its own additive inverse); the rational numbers, by including a multiplicative inverse (1/n) for each integer number n; the real numbers by including with the rationals the (converging) Cauchy sequences of rationals; the complex numbers, by including with the real numbers the unresolved square root of minus one; and so on. These chains of extensions make the natural numbers canonically embedded (identified) in the other number systems.
A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.
In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.

What are natural numbers We learn natural numbers by taking help of counting. Look around you, you will find so many things now count those things. You will count as 1 2 3 4 5 6 7 8 9 10..... and so on. Now look at the numbers which you used while counting you used 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ....and so on. These numbers help us while counting. And these numbers are natural numbers. So we can define natural numbers as the numbers which are used while counting are called as natural numbers. Now we take few examples 1, 34, 4678, 2100, 24045 are all natural numbers And 0, -1, -234, 4.99, 3/4 , all are not natural numbers. SSSS KK KK IIIIIIIIIIIIIIIII LL SS SS KK KK III LL SS ...

The Mathologer sets out to make sense of 1+2+3+ ... = -1/12 and some of those other notorious, crazy-looking infinite sum identities. The starting point for this video is the famous letter that led to the discovery of self-taught mathematical genius Srinivasa Ramanujan in 1913 (Ramanujan is the subject of the movie "The man who knew infinity" that just started showing in cinemas.) Find out about how these identities come up in Ramanujan's work, the role of "just do it" in math, the rules for adding infinite sums on Earth and other worlds, and what all this has to do with the mathematical super star the Riemann Zeta function. You can download the jpeg of Ramanujan's letter to Hardy that I put together for this video here: http://www.qedcat.com/misc/ramanujans_letter.jpg (quite large) You c...
We introduce the realm of natural number multisets Mset(n) for a fixed natural number n. Such msets are k-msets from n, where k is now allowed to be variable. We observe that the realm operations from the natural numbers that we introduced in our last video, namely addition, union and intersection, can now be naturally incorporated into this wider arena, and that the realm laws of arithmetic we discussed apply almost automatically in this set-up.

Here we look at a somewhat unfamiliar aspect of arithmetic with natural numbers, motivated by operations with multisets, and ultimately forming a main ingredient for that theory. We look at natural numbers, together with 0, under three operations: addition, union and intersection. We will somewhat informally at this point refer to this as the `realm' of natural numbers. In this video we lay out some of the rather obvious properties that these three operations satisfy. There are some surprises here: in particular we see an unusual new kind of distributive law which will become the basis for the `tropical calculus'.

Please feel free to leave comments/questions on the video and practice problems below! In this video, I discuss the von Neumann construction of the natural numbers and relate the idea of natural numbers to inductive sets. The axiom of infinity is also introduced here as one of the ZFC axioms.
We introduce some deceptively simple but important notation to deal with multisets/msets from n, for some natural number n. In particular we augment addition of msets with multiples of an mset, and use that to give a list-theoretic description of the multiplicity of various elements that appear in a given mset. In particular this suggests the possibility of extending multiplicities to have negative, or even rational number values. Both of these ideas will have major consequences as we use data structures to help us structure parts of modern algebra.
