Definition

1. Noun:
   • A system of computation using Arabic (decimal) numerals: "algorism" refers specifically to the method or process of performing arithmetic calculations using the digits 0 through 9 and the decimal place-value system.
   • The Arabic or decimal system of numeration: It can also denote the numeral system itself, which uses ten digits and a base of ten, originating from Arabic mathematics.

Usage Examples

• Noun:
  • The introduction of algorism to medieval Europe revolutionized mathematics.
  • Students learning basic arithmetic are mastering the principles of algorism.

Advanced Usage

• Historical Context: The term is often used in historical discussions about the transmission of mathematical knowledge.
  • Algorism, derived from the name of the Persian mathematician al-Khwarizmi, replaced Roman numerals for calculation.

Variants and Related Words

• Algorithm (n): A step-by-step procedure for solving a problem or accomplishing a task, especially in computing. While related historically, "algorithm" has a broader, more modern meaning than "algorism."
  • The search engine uses a complex algorithm to rank web pages.

Synonyms

• Decimal arithmetic: Computation using the base-ten number system.
• Decimal system: The system of writing numbers based on powers of ten.

Notes on Meaning

• Distinction from "Algorithm": It is crucial to distinguish "algorism" from the more common word "algorithm." "Algorism" is specifically about the decimal number system and calculation with it. "Algorithm" refers to any systematic procedure or formula.
