The form of the obelus as a horizontal line with a dot above and a dot below, ÷, was first used as a symbol for division by the Swiss mathematician Johann Rahn in his book Teutsche Algebra in 1659. This gave rise to the modern mathematical symbol ÷, used in anglophone countries as a division sign.

What is the long division thing called?
Who came up with long division?

Who invented zero Ramanujan?

What is the history of the division sign?
It was introduced by the Swiss mathematician, Johann Heinrich Rahn, in his work Teutsche Algebra(1659). This division sign is very graphic, to the point that the bar of the fraction is a general norm. This symbol was not very successful in his home country of Switzerland or in Europe. However, it was in both Britain and the United States.
What is the symbol for Division in math?
One of the division symbols still in use is a bar with a point above and below. It was introduced by the Swiss mathematician, Johann Heinrich Rahn, in his work Teutsche Algebra(1659). This division sign is very graphic, to the point that the bar of the fraction is a general norm.
What is the Anglo-American symbol for Division?
It is an Anglo-American symbol for division is of 17th century origin, and it has been used a long to indicate subtraction on the continent of Europe. Like most elementary combinations of lines and points, the symbol is old. In Zurich in 1659 the Anglo-American symbol obelus first used in the Teutsche Algebra by Johann Heinrich Rahn.
What is the origin of the obelus symbol for Division?
In mathematicsEdit. The obelus was first used as a symbol for division in 1659 in the algebra book Teutsche Algebra by Johann Rahn. Some think that John Pell, who edited the book, may have been responsible for this use of the symbol. Other symbols for division include the slash or solidus (/), the colon (:), and the fraction bar…
