0 what is this?

Answer 1

0 - Zero, Shunya - The state of nothingness. A state of any set which includes no elements at all.

The first thing to say about zero is that there are two uses of zero which are both extremely important but are somewhat different. One use is as an empty place indicator in our place-value number system. Hence in a number like 2106 the zero is used so that the positions of the 2 and 1 are correct. Clearly 216 means something quite different. The second use of zero is as a number itself in the form we use it as 0.

The other term is the state of nothingness, any number multiplied by zero has to be zero. No other number can be divided by zero as zero stands for nothing. But any zero divided by any number is lawyas zero.

Zero appears in the Hindu number system, which is used by all humanity today was developed by 6th century Indian mathematician Brahmagupta. By the mid 2nd millennium BC, the Babylonians had a sophisticated sexagesimal positional numeral system. The lack of a positional value (or zero) was indicated by a space between sexagesimal numerals. By 300 BC a punctuation symbol (two slanted wedges) was co-opted as a placeholder in the same Babylonian system. In a tablet unearthed at Kish (dating from perhaps as far back as 700 BC), the scribe Bêl-bân-aplu wrote his zeroes with three hooks, rather than two slanted wedges.

The Babylonian placeholder was not a true zero because it was not used alone. Nor was it used at the end of a number. Thus numbers like 2 and 120 (2×60), 3 and 180 (3×60), 4 and 240 (4×60), et al., looked the same because the larger numbers lacked a final sexagesimal placeholder. Only context could differentiate them.

Records show that the ancient Greeks seemed unsure about the status of zero as a number: they asked themselves "How can nothing be something?", leading to interesting philosophical and, by the Medieval period, religious arguments about the nature and existence of zero and the vacuum. The paradoxes of Zeno of Elea depend in large part on the uncertain interpretation of zero.

Early use of something like zero by the Indian scholar Pingala (circa 5th-2nd century BC), implied at first glance by his use of binary numbers, is only the modern binary representation using 0 and 1 applied to Pingala's binary system, which used short and long syllables (the latter equal in length to two short syllables), making it similar to Morse code. Nevertheless, he and other Indian scholars at the time used the Sanskrit word śūnya (the origin of the word zero after a series of transliterations and a literal translation) to refer to zero or void.

Rules of Brahmagupta

The rules governing the use of zero appeared for the first time in Brahmagupta's book Brahmasputha Siddhanta, written in 628. Here Brahmagupta considers not only zero, but negative numbers, and the algebraic rules for the elementary operations of arithmetic with such numbers. In some instances, his rules differ from the modern standard. Here are the rules of Brahamagupta:
The sum of two positive quantities is positive
The sum of two negative quantities is negative
The sum of zero and a negative number is negative
The sum of zero and a positive number is positive
The sum of zero and zero is zero.
The sum of a positive and a negative is their difference; or, if they are equal, zero
In subtraction, the less is to be taken from the greater, positive from positive
In subtraction, the less is to be taken from the greater, negative from negative
When the greater however, is subtracted from the less, the difference is reversed
When positive is to be subtracted from negative, and negative from positive, they must be added together
The product of a negative quantity and a positive quantity is negative
The product of a negative quantity and a negative quantity is positive
The product of two positive, is positive.
Positive divided by positive or negative by negative is positive
Positive divided by negative is negative. Negative divided by positive is negative
A positive or negative number when divided by zero is a fraction with the zero as denominator
Zero divided by a negative or positive number is either zero or is expressed as a fraction with zero as numerator and the finite quantity as denominator
Zero divided by zero is zero.

In saying zero divided by zero is zero, Brahmagupta differs from the modern position. Mathematicians normally do not assign a value, whereas computers and calculators will sometimes assign NaN, which means "not a number." Moreover, non-zero positive or negative numbers when divided by zero are either assigned no value, or a value of unsigned infinity, positive infinity, or negative infinity. Once again, these assignments are not numbers, and are associated more with computer science than pure mathematics, where in most contexts no assignment is made.

Positional notation without the use of zero (using an empty space in tabular arrangements, or the word kha "emptiness") is known to have been in use in India from the 6th century. The earliest certain use of zero as a decimal positional digit dates to the 9th century. The glyph for the zero digit was written in the shape of a dot, and consequently called bindu ("dot").

The Hindu numeral system(base 10) reached Europe in the 11th century, via the Iberian Peninsula through Spanish Muslims the Moors, together with knowledge of astronomy and instruments like the astrolabe, first imported by Gerbert of Aurillac. So in Europe they came to be known as "Arabic numerals".

What is certain is that by around 650AD the use of zero as a number came into Indian mathematics. The Indians also used a place-value system and zero was used to denote an empty place. In fact there is evidence of an empty place holder in positional numbers from as early as 200AD in India but some historians dismiss these as later forgeries. Let us examine this latter use first since it continues the development described above.

In around 500AD Aryabhata devised a number system which has no zero yet was a positional system. He used the word "kha" for position and it would be used later as the name for zero. There is evidence that a dot had been used in earlier Indian manuscripts to denote an empty place in positional notation. It is interesting that the same documents sometimes also used a dot to denote an unknown where we might use x. Later Indian mathematicians had names for zero in positional numbers yet had no symbol for it. The first record of the Indian use of zero which is dated and agreed by all to be genuine was written in 876.

We have an inscription on a stone tablet which contains a date which translates to 876. The inscription concerns the town of Gwalior, 400 km south of Delhi, where they planted a garden 187 by 270 hastas which would produce enough flowers to allow 50 garlands per day to be given to the local temple. Both of the numbers 270 and 50 are denoted almost as they appear today although the 0 is smaller and slightly raised.

We now come to considering the first appearance of zero as a number. Let us first note that it is not in any sense a natural candidate for a number. From early times numbers are words which refer to collections of objects. Certainly the idea of number became more and more abstract and this abstraction then makes possible the consideration of zero and negative numbers which do not arise as properties of collections of objects. Of course the problem which arises when one tries to consider zero and negatives as numbers is how they interact in regard to the operations of arithmetic, addition, subtraction, multiplication and division. In three important books the Indian mathematicians Brahmagupta, Mahavira and Bhaskara tried to answer these questions.

Answer 2

Acutally the different solutions are the two thoroughly incorrect or basically partly excellent. No, that may not a 2000, in reality the final year of this physique style became into 1998. And the 1st year became into 1995. 1994 nevertheless had the grille from 1991 in it. Going off the obtrusive clues, it somewhat is a 1995- 1998 Chevrolet K1500. GM constantly used the ok designation to notice four wheel force, C became into 2 wheel. This one sounds like a 1500, which might recommend a million/2 ton. 2500 is the designation for 3/4 ton and 3500 is the designation for a million ton. What this one probably is, is a 1996 to 1998 judging from some different tricks which is composed of the form of the mirrors.

Answer 3

0 it the beginning

Answer 4

Zero is merely an option to adjust the numbers. It values when it stands with another figure. Sir CV Raman asked " if zero is multiplied by any figure the answer is zero, naturally when zero is divided by a figure, the answer must be zero".
Great Mathematicians has not uet accepted this. They say it can not be divided. (If divided, the whole mathematics would change the world). This is my shame about your question.

Answer 5

It is a element of number system invented by Indians.

It shows the life is a cycle and it has ups and downs. Every one can come up from the bottom and any one can fall down.

Answer 6

Zero..it is a # which cums b4 one!!
And Mr. cdavis999 let me clarify that the whole numerals from 0-9 was stolen from ARABs .... I dont think u ever knew dis...!!

Answer 7

It is in English referred to as "zero." It is a symbol, and as such only has meaning assigned to it by those who share a common understanding of what it signifies. Without that common understanding, it is nothing more than a squiggle on the screen.

And to those who wish to use their imaginations, it can become whatever they want it to be. I choose to see it as a Jelly Doughnut.

^v^ ^v^ ^v^ ^v^ ^v^ ^v^ ^v^ ^v^

Answer 8

The binary compliment of this: 1

Answer 9

A strong number that affects positevely when you put it on the right to another number and does nothing when put on the left.

Answer 10

The perfect amount. Anymore than that leads to greed.

Answer 11

It is a mathematical representation of the absence of quantity.
