Claim: The word 'algorithm' has its roots in the name of the Persian mathematician of al-Khwarizmi (Algoritmi in Latin). The modern concept of the algorithm was later formalized by David Hilbert around 1928.
Fact: Al-Khwarizmi wrote, “Kitab al hisab al Hindi”( “book of Hindu numericals”). This was translated into Latin by the name “Algorithmi de Numero Indorum” (“Al-Khwarizmi's Indian numericals”). This book's name was abbreviated as “Algorithm”. That is how the world knows it today
