### Random information on the term “NIL”:

0 (zero; BrE: /ˈzɪərəʊ/ or AmE: /ˈziːroʊ/) is both a number and the numerical digit used to represent that number in numerals. The number 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. Names for the number 0 in English include zero, nought or (US) naught (/ˈnɔːt/), nil, or—in contexts where at least one adjacent digit distinguishes it from the letter “O”—oh or o (/ˈoʊ/). Informal or slang terms for zero include zilch and zip. Ought and aught (/ˈɔːt/), as well as cipher, have also been used historically.

The word zero came into the English language via French zéro from Italian zero, Italian contraction of Venetian zevero form of ‘Italian zefiro via ṣafira or ṣifr. In pre-Islamic time the word ṣifr (Arabic صفر) had the meaning ’empty’. Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: शून्य) from India. The first known English use of zero was in 1598.

### Random information on the term “NADA”:

Nothing is a concept denoting the absence of something, and is associated with nothingness. In nontechnical uses, nothing denotes things lacking importance, interest, value, relevance, or significance. Nothingness is the state of being nothing, the state of nonexistence of anything, or the property of having nothing.

Some would consider the study of “nothing” to be foolish. A typical response of this type is voiced by Giacomo Casanova (1725–1798) in conversation with his landlord, one Dr. Gozzi, who also happens to be a priest:

However, “nothingness” has been treated as a serious subject for a very long time. In philosophy, to avoid linguistic traps over the meaning of “nothing”, a phrase such as not-being is often employed to make clear what is being discussed.

One of the earliest western philosophers to consider nothing as a concept was Parmenides (5th century BC), who was a Greek philosopher of the monist school. He argued that “nothing” cannot exist by the following line of reasoning: To speak of a thing, one has to speak of a thing that exists. Since we can speak of a thing in the past, this thing must still exist (in some sense) now, and from this he concludes that there is no such thing as change. As a corollary, there can be no such things as coming-into-being, passing-out-of-being, or not-being.

### Random information on the term “ZERO”:

In complex analysis, a zero (sometimes called a root) of a holomorphic function f is a complex number a such that f(a) = 0.

A complex number a is a simple zero of f, or a zero of multiplicity 1 of f, if f can be written as

where g is a holomorphic function such that g(a) is nonzero.

Generally, the multiplicity of the zero of f at a is the positive integer n for which there is a holomorphic function g such that

The multiplicity of a zero a is also known as the order of vanishing of the function at a.

The fundamental theorem of algebra says that every nonconstant polynomial with complex coefficients has at least one zero in the complex plane. This is in contrast to the situation with real zeros: some polynomial functions with real coefficients have no real zeros. An example is f(x) = x2 + 1.

An important property of the set of zeros of a holomorphic function of one variable (that is not identically zero) is that the zeros are isolated. In other words, for any zero of a holomorphic function there is a small disc around the zero which contains no other zeros. There are also some theorems in complex analysis which show the connections between the zeros of a holomorphic (or meromorphic) function and other properties of the function. In particular Jensen’s formula and Weierstrass factorization theorem are results for complex functions which have no counterpart for functions of a real variable.
