Division is the inverse of multiplication, meaning that multiplying and then dividing by the same non-zero quantity, or vice versa, leaves an original quantity unchanged; for example () / = (/) =. [12]
"Division by Zero" is a science fiction short story by American writer Ted Chiang, initially published in 1991 in Full Spectrum 3 magazine [2] [3] and subsequently republished in the 2002 Ted Chiang collection Stories of Your Life and Others.
In these enlarged number systems, division is the inverse operation to multiplication, that is a = c / b means a × b = c, as long as b is not zero. If b = 0, then this is a division by zero, which is not defined. [a] [4]: 246 In the 21-apples example, everyone would receive 5 apple and a quarter of an apple, thus avoiding any leftover.
In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept called mathematical fallacy.There is a distinction between a simple mistake and a mathematical fallacy in a proof, in that a mistake in a proof leads to an invalid proof while in the best-known examples of mathematical fallacies there is some element of concealment or ...
In particular, division by zero is meaningful. The real numbers can be extended to a wheel, as can any commutative ring . The term wheel is inspired by the topological picture ⊙ {\displaystyle \odot } of the real projective line together with an extra point ⊥ ( bottom element ) such that ⊥ = 0 / 0 {\displaystyle \bot =0/0} .
Division by zero is considered impossible at an elementary arithmetic level. Two numbers can be divided on paper using long division. An abbreviated version of long division, short division, can be used for smaller divisors.

[1] [2] Since division of integers by zero is undefined, this definition has meaning only if a and b are both different from zero. [3] However, some authors define lcm(a, 0) as 0 for all a, since 0 is the only common multiple of a and 0.
