Algebra into Europe in the 12th century until its triumph in the 16th.[1]

Algorism is the technique of performing basic

place value form and applying a set of memorized rules and facts to the digits. One who practices algorism is known as an algorist. This positional notation system has largely superseded earlier calculation systems that used a different set of symbols for each numerical magnitude, such as Roman numerals, and in some cases required a device such as an abacus
.

Etymology

The word algorism comes from the name

Alexandre de Villedieu
. It begins thus:

Haec algorismus ars praesens dicitur, in qua / Talibus Indorum fruimur bis quinque figuris.

which translates as:

This present art, in which we use those twice five Indian figures, is called algorismus.

The word algorithm also derives from algorism, a generalization of the meaning to any set of rules specifying a computational procedure. Occasionally algorism is also used in this generalized meaning, especially in older texts.

History

Starting with the

decimal point. This system was popularized in Europe by Leonardo of Pisa, now known as Fibonacci.[11]
