Hi ravi,

That is nice. Can you tell me what zero BY zero is? It is not one of course

Hi,

You are both right. but 0/0 is nothing ,null(indeterminate), infinite(true for any number by zero). As I am fond of saying ONLY INDIAN CONTRIBUTION TO MATHEMATICS IS ZERO  in my lectures and presentation to provoke the participants, yes zero was discovered by brahma putra

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 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
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 done

also algebra is
Elementary algebra
The number 0 is the least non-negative integer. The natural number following 0 is 1 and no natural number precedes 0. The number 0 may or may not be considered a natural number, but it is a whole number and hence a rational number and a real number (as well as an algebraic number and a complex number).

The number 0 is neither positive nor negative, neither a prime number nor a composite number, nor is it a unit. It is, however, even (see evenness of zero).

The following are some basic (elementary) rules for dealing with the number 0. These rules apply for any real or complex number x, unless otherwise stated.

Addition: x + 0 = 0 + x = x. That is, 0 is an identity element (or neutral element) with respect to addition.
Subtraction: x − 0 = x and 0 − x = − x.
Multiplication: x · 0 = 0 · x = 0.
Division: 0/x = 0, for nonzero x. But x/0 is undefined, because 0 has no multiplicative inverse, a consequence of the previous rule; see division by zero. In the real numbers, for positive x, as y in x/y approaches 0 from the positive side, the quotient increases indefinitely toward positive infinity, but as y approaches 0 from the negative side, the quotient tends toward negative infinity.
Exponentiation: x0 = 1, except that the case x = 0 may be left undefined in some contexts; see Zero to the zero power. For all positive real x, 0x = 0.
The expression 0/0, which may be obtained in an attempt to determine the limit of an expression of the form f(x)/g(x) as a result of applying the lim operator independently to both operands of the fraction, is a so-called "indeterminate form". That does not simply mean that the limit sought is necessarily undefined; rather, it means that the limit of f(x)/g(x), if it exists, must be found by another method, such as l'Hôpital's rule.

The sum of 0 numbers is 0, and the product of 0 numbers is 1.
