i A A number jA\pITOB Number (Kazusa, numeral, number) and is an abstract concept used to describe any quantity. Rs[^l ijB In certain areas such as computer numeric (amount) also called.
AA{IB Number and the number has been frequently confused, and may not to confuse the issue, are essentially different. \A\L i jB While the number is expressed as the number of objects, numbers and symbols to represent the number of (character).
A S11AoA1B For example, apples and oranges that there is one piece that is completely different, some common to find that there are calling it one. 1 SAcZB One of the few is not apples and oranges, not to say that the short segments drawn in the vertical and horizontal.

TOljgB Several concepts have been gradually expanding with the history of mankind. fpARB As several of the most simple, is a natural number as a number of things. AlLA lZRsnB Integer is added to an integer from the negative, was obtained and the rational thinking of a commercial integer can allow the system to free the four arithmetic operations. LgZMbvA@fB Extension to real numbers from rational calculation like this is immediately available to fill a gap in a different way from the complex, including the imaginary through the solution of algebraic equations.
A if jSWwlB In general, the number is real (and sometimes complex) is thought to refer to include the whole set. nAuvB While this system is also different, some of it was also "a few" called. ATORgA\Rg`B For example, a base to expand the concept of natural number is a number of things, be defined as an extension of the ordinal number in the sense of representing the natural order of things. ALssf pp -iAfOAnl A E\ZB The prime in parallel with the transition to a real rational number p for each p - or decimal there, have a more imaginary outside the complex, quaternion system lost its nature as a treatment for some of them, 8 There are several original and the number 60. AnB Alternatively, some systems such as real-containing large infinitely small and infinite in addition to the real numbers.
dv_A|lXZ{B The important point about the number, that can add or subtract or multiply or divide among the people that perform the operations. lZQB For more information and was referred to a term of four arithmetic operations.
ZA wwA QEE`c_B For such an operation in the algebra of abstract mathematics, it is the argument that a more generalized form of the body, such as algebra.
@\@L@B Methods that represent the numbers and how the number is called a notation. AL@\B The same number can have multiple view of the notation is not uncommon. AL@@\B In fact, in some kind of notation is to be broken in only one way to do it. A\i\ 1 = 0.999... iEA_S 9j\B For example, the display is a decimal number decimal = 0.999 ... (right side, all digits following the decimal 9) with a view of the two.
