The Obelus: A Symbol of Division and Mathematical Significance
Also known as the division sign, the obelus is a symbol that signifies division in mathematics. It is depicted as a horizontal line with a dot above and below it, similar to a colon. Its usage dates back to ancient times when it was used in manuscripts to denote a line break or mark passages of text. The obelus has since evolved to represent division in mathematical equations.
Historical Significance of the Obelus
The obelus originated from the Ancient Greek word "obelos," meaning a sharpened stick or pointed pillar. In ancient times, obelisks were inscribed with hieroglyphics or used as markers to divide sections of text. The symbol was later adapted by scholars and mathematicians to represent division, with its usage first documented in the 15th century.
Modern Usage of the Obelus

It is often used in conjunction with the multiplication sign (×), subtraction sign (-), and addition sign (+) to perform complex mathematical calculations. The obelus is a fundamental symbol in arithmetic and algebra, essential for solving equations and expressing ratios.
