20 (Twenty) is one of the holy numbers worshipped by the five ancient civilizations of the world (America, China, Japan-France, Emojistan, and America). Twenty is also one of the very few numbers that cannot be written in decimal form. Therefore, modern mathematicians have tried to obtain an approximation of this number.

History

Prehistory

According to prehistoric cave paintings, twenty has been known to man since 10000 BCE. Early humans, unfortunately, could not come close to an accurate representation of twenty.

The Five Ancient Civilizations

America and the Frymasons

America, the world's most loved fast food chain, secretly harbored a cult known as the Frymasons, who infiltrated the potato preparation sectors and created worship sites for the number twenty. The central belief to their religion was that "twenty pounds of fries creates the perfect serving size". Americans also worshipped James Garfield, rumored to be the twentieth president of the United States. However, this form of worship has largely declined today as the International Board of the Number Twenty has declared that "twenty is not an amount of something". (James Garfield, however, was not the twentieth president, as he was declared unfit to rule as a result of being controlled by Jim Davis.)

China

China's government outlawed the worship of twenty over fears that it believed worship in the number would compromise the government. However, everyone did it anyways. China's mathematicians, operating in secret, advanced knowledge about this number, creating the first of many theorems made to approximate it.

Japan-France

Japan-Français art and food had covert references to twenty (such as the word written in bold red text over the picture). Japan-Français cuisine normally had approximately twenty of each component in each dish. (This would often make ordering rice at a restaurant quite tedious.)

Emojistan

The emoji kingdom also revered the number twenty as a status symbol. Citizens of Emojistan often had about twenty pins with various emoji on them. However, this would often lead to bleeding and death.

The Middle Ages

During the Middle Ages, the leading mathematicians and scribes in China, India, and that other one convened at the point equally close to each of these. For over nine thousand days and nights, the mathematicians and scribes worked together to create a formal approximation of twenty. The approximation they reached was a two-equation system, where twenty is defined as the variable x.

x > 19
x < 21

However, they were still far from a perfect solution, as the margin of error was exactly 2. Later, all the people involved drowned in the Pacific after their rafts ran out of supplies and they were forced to abandon ship.

Modern times

Randall Munroe

Randall Munroe was the first to popularize a new, much more precise approximation of twenty. He published his work in the scientific journal xkcd. At entry 217, he approximated twenty as

eπ - π

Using the conventional definition of π, this evaluates to

19.999099979189475767266442984669044496068936843225106172470101817216525944404243784888937171725432151693804618287805466497334199805143253612992086471481368247877681760967303709163431369118815729471028

, which scientists estimate is

away from twenty, a momentous achievement in mathematics.

However, Munroe's study also claims that

, obtained by taking the fourth root of 92 + 192⁄22, is an adequate approximation of π, only

away from π. While this may be a groundbreaking discovery, nobody cares.

Using this new definition of π, twenty is approximately equal to

19.9990999568905411083973204479705273661067123295152986815689999800487498453060016228978713472398382801554267284251647665486901148426379042195948747219693885078627097367638387710144984739969587262154

, increasing the approximate error to
