The contributions of German cossists in the 16th and early 17th century
The reduction of theoretically possible 27 types of quadratic equations to eight by Christoff Rudolff mirrors the concern about the domain of admissible (positive) values of the roots. When Michael Stifel a generation later had reduced the solution of these eight different types of quadratic equations to one single rule he lived up to the expectations of the clients of German reckoningmasters who were accustomed to receive recipelike algorithmic rules for the solution without any proof or even hint of an understanding. This form of algorithmic rules for the solution of a problem is still preserved in the rules for finding the tangent or extreme values of Fermat. An interesting case to test the extension of the domain of admissibles values for the roots of an equation is the reception of Cardano's rules for the solution of cubic equations in Germany. It can be shown that Michael Stifel and Johannes Junge, who both treated cubic equations, modified Cardano's rules in a way that the roots fell still in the domain of Euclidean irrationalities. Only in the early 17th century cossists like Johannes Faulhaber and Peter Roth, to whom we owe one form of the fundamental theorem of algebra, accepted radicals with exponent three, albeit no complex solutions like Bombelli in Italy. In Faulhaber's

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 root were indicated by
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.

Introduction
The constant 2 is famous because it's probably one of the first irrational numbers discovered. According to the Greek philosopher Aristotle (384-322 BC), it was the Pythagoreans around 430 BC who first demonstrated the irrationality of the diagonal of the unit square and this discover was terrible for them because all their system was based on integers and fractions of integers. Later, about 2300 years ago, in Book X of the impressive Elements, Euclid (325-265 BC) showed the irrationality of every nonsquare integer (consult [ ] for an introduction to early Greek Mathematics). This number was also studied by the ancient Babylonians. The history of the famous sign goes back up to 1525 in a treatise named Coss where the German mathematician Christoff Rudolff (1499-1545) used a similar sign to represent square roots.

Dear members of the list,
I am concerned with details of the life and manuscripts including letters
of Peter Roth of whom very little is known. I can provide you with the
following informations: Roth worked in the German city Nuremberg as a
reckoningmaster until his death in 1617. Nothing is known about the place
and date of his birth.
He published in 1608 a book in Nuremberg the full title of which is:
