2 + 2 = 5

2 + 2 = 5 or two plus two equals five is a mathematical falsehood which is used as an example of a simple logical error that is obvious to anyone familiar with basic arithmetic.

The phrase has been used in various contexts since 1728, and is best known from the 1949 dystopian novel Nineteen Eighty-Four by George Orwell.

As a theme and as a subject in the arts, the anti-intellectual slogan 2 + 2 = 5 pre-dates Orwell and has produced literature, such as Deux et deux font cinq (Two and Two Make Five), written in 1895 by Alphonse Allais, which is a collection of absurdist short stories; and the 1920 imagist art manifesto 2 × 2 = 5 by the poet Vadim Shershenevich.

Okay I am pretty sure it must be a satire page correct? I do not understand its purpose or why its on hackernews tho.
