'algorismic' originates from 'algorithm', which comes from the name of the Persian mathematician 'Al-Khwarizmi', whose works introduced the decimal positional number system to the Western world.

'algorithm' changed from the Latin word 'algorismus', which was derived from the name 'Al-Khwarizmi', and eventually became the modern English word 'algorithm'.

Initially, it referred to the process of calculation using Arabic numerals, but over time it evolved into its current meaning of a step-by-step procedure for calculations.
