His name gave rise to the terms "algorism" and "algorithm". One who practices algorism is known as an algorist. The terms algorism and algorithm are derived from the European version of his name. There were 1,000 to 1,200 children learning to use the abacus and algorism for mathematics. This study is sometimes known as algorism. Occasionally "algorism" is also used in this generalized meaning, especially in older texts.
