The Birth Of Algebra In Germany, christoff rudolff (1499 1555) wrote a book in 1525 called simply Coss.The Italian algebraists had identified the unknown value in a problem http://cerebro.xu.edu/math/math147/02f/algebra/algebra.html
Extractions: In the year AD 312, on the eve of a battle against would-be rivals for the Roman Imperial throne, Constantine had a dream that instructed him to place the chi rho , the Christian symbol formed by superimposing the first two letters of the Greek name Christos , on the shields of his soldiers. When he won the battle and became Emperor, he issued an edict of tolerance for Christian believers. Later, on his deathbed, Constantine himself became a Christian, placing it in a position of prominence in the Empire from which it would influence the history of the Western world to this day. In 324, Constantine moved the seat of the Empire to the Greek town of Byzantium in the east of the empire, renaming it Constantinople after himself. His was one of the last strong governments of the Roman Empire. The tenuous union of the eastern and western halves of the empire during the fourth century continued to fray, so that by the year 400 it had split in two for good. The Goths entered Rome in 476 , bringing down the Western Empire. This marks the start of the Middle Ages, when Greek culture was effectively cut off from the West. Tribal governments held sway, giving way to feudal society and the slow development over centuries of what would eventually become the familiar nation-states of Europe.
Part II Outline examples of this development appear in France in the work of Nicholas Chuquet,in Germany by christoff rudolff, and in England by Robert Recorde. http://cerebro.xu.edu/math/math147/02f/part2/part2.html
Origins Of Some Arithmetic Terms-4 According to Jeff Miller s web site, The radical symbol first appeared in 1525in Die Coss by christoff rudolff (14991545). http://www.pballew.net/arithme4.html
Extractions: Math Words, pg 4 Back to Math Words Alphabetical Index Add / Addition The arithmetic word add is from the Latin root addere , to give or to do. The dere part of the root is the same root that gives us Data/Datum and the name for dice . Donation and condone also share the same root. The first recorded use of the word in English is from "The Crafte of Nombrynge" according to Jeff Miller's web site . The document was one of the first English language documents dealing with mathematics. The symbol "+" for addition was used for surplus and deficit before it was used as an operation symbol. It has been shown that the symbol was used on barrels to mark them as over or under weight prior to the earliest known use in manuscripts. Some even suggest it dates back to the Early Greeks, but others suggest it is a short form of the script word et , Latin for and. The symbol seems to have been first used for an operation in the late 1400's and only came into common usage after it was used by Robert Recorde in his 1557 book, The Whetstone of Witte

Extractions: O símbolo de raiz apareceu pela primeira vez em 1525 no livro de álgebra Die Cross , da autoria de CHRISTOFF RUDOLFF (1499-1545), porém sem índices que indicassem a natureza da raiz (ou seja, se era raiz quadrada, cúbica, de quarta potência...). O símbolo (sem o travessão) pode ter sido usado por se parecer com a forma manuscrita do r da palavra radix , ou pode ter mesmo sido uma invenção arbitrária. Este símbolo criado por RUDOLFF não teve aceitação imediata nem mesmo na Alemanha, sua terra natal. A letra l (do latim latus , lado) era muita vezes utilizada.

Sirve para medir la ley; en este caso el objeto de oro tiene una ley de 16 quilates. El origen de los signos + y - El signo = para las igualdades fue utilizado por primera vez por el inglés Robert Recorbe en 1557 apareciendo por primera vez en su libro "El aguzador del ingenio", siendo el primer tratado inglés de álgebra. Según el autor, eligió ese símbolo porque dos cosas no pueden ser más iguales que dos rectas paralelas.
