What is a "ZERO"? Importance of zero in matematics?

Answer 1

0 (zero) is both a number and the numerical digit used to represent that number in numerals. It plays a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, zero is used as a placeholder in place value systems. Historically, it was the most recent digit to come into use. In the English language, zero may also be called null or nil when a number, "oh" (IPA: [oʊ]) or cipher (archaic) when a numeral, and nought or naught[1] in either context

Answer 2

0 is the integer that precedes the positive 1, and follows −1. In most (if not all) numerical systems, 0 was identified before the idea of 'negative integers' was accepted.

Zero is an integer which quantifies a count or an amount of null size; that is, if the number of your brothers is zero, that means the same thing as having no brothers, and if something has a weight of zero, it has no weight. If the difference between the number of pieces in two piles is zero, it means the two piles have an equal number of pieces. Before counting starts, the result can be assumed to be zero; that is the number of items counted before you count the first item and counting the first item brings the result to one. And if there are no items to be counted, zero remains the final result.

While mathematicians all accept zero as a number, some non-mathematicians would say that zero is not a number, arguing one cannot have zero of something. Others hold that if you have a bank balance of zero, you have a specific quantity of money in your account, namely none. It is that latter view which is accepted by mathematicians and most others.

Almost all historians omit the year zero from the proleptic Gregorian and Julian calendars, but astronomers include it in these same calendars. However, the phrase Year Zero may be used to describe any event considered so significant that it virtually starts a new time reckoning.

Answer 4

Importance of Zero
The importance of the creation of the zero mark can never be exaggerated. This giving to airy nothing, not merely a local habitation and a name, a picture, a symbol, but helpful power, is the characteristic of the Hindu race from whence it sprang. It is like coining the Nirvana into dynamos. No single mathematical creation has been more potent for the general on-go of intelligence and power. [G.B. Halsted]

Dividing by zero...allows you to prove, mathematically, anything in the universe. You can prove that 1+1=42, and from there you can prove that J. Edgar Hoover is a space alien, that William Shakespeare came from Uzbekistan, or even that the sky is polka-dotted. (See appendix A for a proof that Winston Churchill was a carrot.) [Charles Seife], from: Zero: The Biography of a Dangerous Idea

Answer 5

Zero is important for a few reasons. It is the start of the decimal system which is counted from 0 to 9, not 1-10; as such, it also represents powers of ten as in 10, 100, 1000, etc; lastly, it represents nothing which seems insignificant but it is undeniable to have a complex mathematics system to explain the workings of the universe (calculus, geometry, algebra) without a number representing nothing as a base.

Answer 7

Zero is a mathematical digit found by Indians.

Importance of zero can be explained in a small example.....

consider 01 and 10...compare between 01$ and 10$ then you know the importance of zero...

Answer 8

When my parents were in school, they [schooling community] tried to get the children, when counting to start with the zero (zero... one... two... etc.), but that didn't work. :-l

What would you rather have, $1 or $10? $1 or $1000000?

What would you rather owe, $0 or $1? $0 or $1111111?

Answer 9

Zero is nothing (in Value) but the value varies depending
on its position, before or after the number TQ

Answer 10

zero has its importance in digital electronics(binary digits 0 and 1).Its important in mathematics to represent significant digits like 0.0000986 and 9.8600000 both are different where former has got trial zeroes and latter has got trailing zeroes that are used to represent significant digits in the number system.The list goes on.
