In mathematics, a rational number is a number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q. [1] For example, is a rational number, as is every integer (for example, =).
0 (zero) is a number representing an empty quantity.Adding (or subtracting) 0 to any number leaves that number unchanged; in mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures.
Algebraic number: Any number that is the root of a non-zero polynomial with rational coefficients. Transcendental number : Any real or complex number that is not algebraic. Examples include e and π .
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 830, Mahāvīra unsuccessfully tried to correct the mistake Brahmagupta made in his book Ganita Sara Samgraha: "A number remains unchanged when divided by zero ...

So the real number 0.999... is the set of rational numbers such that < 0, or < 0.9, or < 0.99, or is less ... must be smaller than any positive rational number, ...
There is a real number called zero and denoted 0 which is an additive identity, ... a rational number is an equivalence class of pairs of integers, and a real number ...
The additive identity familiar from elementary mathematics is zero, denoted 0.For example, + = = + In the natural numbers (if 0 is included), the integers , the rational numbers , the real numbers , and the complex numbers , the additive identity is 0.
