A second way to show division is to use the obelus ( or division sign ), common in arithmetic, in this manner:

The obelus is also used alone to represent the division operation itself, as for instance as a label on a key of a calculator.

The obelus is believed to have been invented by the Homeric scholar Zenodotus as one of a system of editorial symbols.

Isidore of Seville ( c. 560 – 636 AD ) described the use of the symbol as follows: " The obelus is appended to words or phrases uselessly repeated, or else where the passage involves a false reading, so that, like the arrow, it lays low the superfluous and makes the errors disappear ...

The obelus accompanied by points is used when we do not know whether a passage should be suppressed or not.

An obelus ( symbol: ÷, plural: obeli ) is a symbol consisting of a short horizontal line with a dot above and below.

The obelus, invented by Aristarchus to mark suspected passages in Homer, is frequent in manuscripts of the Gospel to mark just those sections, like the Pericope in John, which modern editors reject.

The obelus is occasionally used in Polish language typography to represent ranges ( such as the range 1 ÷ 10 ).

In Denmark, the obelus is used as the mathematical symbol for " Subtraction ".

In Microsoft Windows, the obelus is produced with Alt + 0247 on the number pad or by pressing Alt Gr, Shift and the "+ =" key.

In the Unicode character set, the obelus is known as the “ division sign ” and has the code point U + 00F7.

In LaTeX, the obelus is obtained by < tt >

In English-speaking countries, long division does not use the slash (/) or obelus (÷) signs, instead displaying the dividend, divisor, and ( once it is found ) quotient in a tableau.

Rahn is credited with the invention of the division sign ÷ ( obelus ); it has also been attributed to Pell, who taught Rahn a three-column spreadsheet-style technique of tabulation of calculations, and acted as editor for Rahn's 1659 book Teutsche Algebra in which it appeared.

# A recension of the Septuagint, with ( 1 ) interpolations to indicate where the Hebrew is not represented in the Septuagint — these are taken mainly from Theodotion's text and marked with asterisks, and ( 2 ) indications, using signs called obeloi ( singular: obelus ), of where words, phrases, or occasionally larger sections in the Septuagint do not reflect any underlying Hebrew.

The system was further refined by his student Aristophanes of Byzantium, who first introduced the asterisk and used a symbol resembling a ⊤ for an obelus ; and finally by Aristophanes ' student, in turn, Aristarchus, from whom they earned the name of ' Aristarchian symbols '.

While the asterisk ( asteriscus ) was used for corrective additions, the obelus was used for corrective deletions of invalid reconstructions.

Some scholars used the obelus and various other critical symbols, in conjunction with a second symbol known as the metobelos (" end of obelus "), variously represented as two vertically arranged dots, a γ-like symbol, a mallet-like symbol, or a diagonal slash ( with or without one or two dots ).

310 – 320 – 403 ) used both a horizontal slash or hook ( with or without dots ) and an upright and slightly slanting dagger to represent an obelus.

The obelus was also occasionally used as a mathematical symbol for subtraction.

Many new readings were inserted in the text with an asterisk affixed, while an obelus was used to mark many others as corrupt.

The obelus was first used as a symbol for division in 1659 in the algebra book Teutsche Algebra by Johann Rahn.

The obelus had been used by some writers to represent subtraction, and that usage continued in some parts of Europe ( including Norway and, until fairly recently, Denmark ).

" In the Septuagint column used the system of diacritical marks which was in use with the Alexandrian critics of Homer, especially Aristarchus, marking with an obelus under different forms, as "./.

The dagger symbol originated from a variant of the obelus ( plural: obeli ), originally depicted by a plain line (-) or a line with one or two dots (÷).

Meanwhile, division was represented with the classic mathematical division symbol ( the obelus, ÷), which was implemented by overstriking a minus sign and a colon ( on both EBCDIC and ASCII paper terminals ).

The word " obelus " comes from, the Greek word for a sharpened stick, spit, or pointed pillar.
