what is 0?

Answer 1

A circle off course.

Answer 2

(zero) is both a number and a numerical digit used to represent that number in numerals. As a number, zero means nothing — an absence of other values. 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 last digit to come into use. In the English language, zero may also be called null or nil when a number, o/oh when a numeral, and naught/naught in either context.

0 as a number

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. It means "courageous one" in hieroglyphics.

Zero is a number 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 that one cannot have zero of something. Others hold that if one has a bank balance of zero, one has a specific quantity of money in that 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 3

0 is nothing

nothing for life and 9 use 0

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

Zero is not "nothing", if zero is nothing then what is negative numbers like -1 or "imaginary" numbers (complex numbers) like i= square root of -1?

Zero is not the least number, -~ (minus infinity) is the least number

Zero is a number of which any numbers added or substracted into will be that number again, and a number of which any number timed into will be zero again.

Many says that zero is just a numerator in modern algebra which derived from Arabic numbers. But zero exists as well complex numbers exist, and manifests physically.

Answer 6

It represents a location at an origin, with reference to a certain frame of reference with fixed dimensions.
If it is 0 for a certain frame of reference, it does not mean it is an absolute zero. It may have some value with reference to some other axis or frame of reference.
Say if some one has zero value in front of you, it does not means that he/she is not important to any one else.

Answer 7

An integer between -1 and 1.
