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

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.

Al-Samawal Born about 1130 in Baghdad,
IraqDied about 1180 in Maragha, Iran
Describing how to construct the third row of
Pascals Triangle, on his way to finding
coefficients for the expansion of
If we transfer the 'one' in the second column
into a third column, then add 'one' from the
second column to 'two' below it, we obtain
'three' to be written under the 'one' in the
third column. If we then add 'two' from the
second column to 'one' below it we have 'three'
which is written under the 'three', then we write
'one' under this 'three' we thus obtain a third
column whose numbers are 'one', 'three', 'three',
and 'one'.

Toledo, Spain School of Translation, 1150
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
