Completing the Square
What is the square which combined with ten of its roots will give a sum total of 39?
Solve
The manner of solving this type of equation is to take one-half of the roots just mentioned. Now the roots in the problem before us are 10. Therefore take 5, which multiplied by itself gives 25, an amount which you add to 39 giving 64. Having taken then the square root of this which is 8, subtract from it half the roots, 5 leaving 3. The number 3 therefore represents one root of this square

MAA Online, March 2003:
“The Liber abaci of Leonardo Pisano (today commonly called Fibonacci) is one of the fundamental works of European mathematics. No other book did more to establish the basic framework of arithmetic and algebra as they developed in the Western world.”

Toledo, SpainSchool of Translation, 1150
View of Toledo by El Greco
Keith Devlin:Latin was the language of the European scholars, and thus the target language for the translations. Since few European scholars knew Arabic, however, the translation was often done in two stages, with a Jewish scholar living in Spain translating from the Arabic to some common language and the visiting scholar then translating from that language into Latin. In the same way, many ancient Greek texts, from Aristotle to Euclid, were also translated into Latin, whereupon they began to make an impact in the West
