§1.1 Roots of the Hindu-Arabic Numbers Introduction The ten symbols 9 which are used today by nearly all peoples represents, to quote Karl Menninger from his excellent book Number Words and Number Symbols , "the world-wide victory of an idea." Few things in our world are universally accepted and continuously ongoing, but the surviving concept that effectively rendered all other numbering systems obsolete is the one handed down to us centuries ago from the Hindus and Arabs. The Hindu-Arabic numbering system is named for the Hindus, who appear to have invented it, and the Arabs, who transmitted it to the West. Although the history of India is beyond our scope, an appreciation for some of its highlights is in order so that we may understand how late - as compared to the Egyptians, Greeks, and Babylonians - it was when India finally stepped up to the proverbial plate and hit a mathematical homerun with her contribution to the world. In looking back, her gift of ten simple symbols combined with a place-valued numbering system may be argued as being the most important of all offerings to mathematics and mankind. The Hindus Of no small consequence is the fact that the northwest part of India (Gandhara) was part of the Persian Empire from the 6 th century B.C. on. In his quest to conquer Persia, Alexander the Great invaded this region around 325 B.C. It was at this time that Greek culture, including mathematics and astronomy, took refuge in India. What is known as Gandhara art is a direct result of the mixture of East and West. Clearly the most important result of this incursion was that now a route for the exchange of ideas and culture existed between India and her distant neighbors to the west.

The Radical Symbol
Before symbols, the words "roots" or "side" were commonly used for the square root of a number. Arab writers thought of a square number as growing out of a root, so Arabs often used the word radix , "extracting," or pulling out, the root. Latin writers thought of it as "finding" the latus, or side of a square. Late medieval Latin writers turned radix into a single symbol R x . This was used for more than one hundred years. The French writer Nicolas Chuquet (1484) sometimes used R x for R x , R x and R x for cube and fourth roots, respectively. The symbol was introduced by Christoff Rudolff in 1525 in his book Die Coss . It is believed this symbol was used because it resembled a small r radix ) at the time. The cube and fourth roots were as shown below:
Cube Root Fourth Root Rudolff's symbol was not immediately used. The letter l (latus, "side") was often used. For example the square root of 4 was l 4 and the third root of 5 was lc 5. By the seventeenth century, the square root symbol was being used regularly even though there were many ways the indices were written for higher roots.

Earliest Uses of Symbols of Operation and Grouping
Last revision: Aug. 15, 1997
ADDITION AND SUBTRACTION SYMBOLS
Plus (+) and minus (-). The plus symbol as an abbreviation for the Latin et (and), though appearing with the downward stroke not quite vertical, was found in a manuscript dated 1417 (Cajori).
The + and - symbols first appeared in print in Mercantile Arithmetic or Behende und hubsche Rechenung auff allen Kauffmanschafft , by Johannes Widmann (born c. 1460), published in Leipzig in 1489. However, they referred not to addition or subtraction or to positive or negative numbers, but to surpluses and deficits in business problems (Cajori vol. 1, page 128).
Cajori says, "There is clear evidence that, as a lecturer at the University of Leipzig, Widmann had studied manuscripts in the Dresden library in which + and - signify operations, some of these having been written as early as 1486." Johnson (page 144) says a series of notes from 1481, annotated by Widmann, contain the + and - symbols, and he asks whether Widman could have copied these symbols from some unknown professor at the University of Leipzig. Johnson also says that a student's notes from one of Widmann's 1486 lectures show the + and - signs.
Giel Vander Hoecke used + and - as symbols of operation in Een sonderlinghe boeck in dye edel conste Arithmetica
