Characteristic of European Middle Ages Mathematics:

Europe had accepted calculus and algebra from India and east counties until 900's. In India Aryabhata(475-553) wrote the numeration system and the astronomical observation theory on Aryabhattiya(449) in 600's. Arabic camber was invented in India.  Italian Fibonacci introduced Arabic number go Europe.

Monastic Mathematics: We call the term the black Age from the middle of 400's to 1000's.  In this times, the church controlled all the action and thinking of humans.  Thus, there was no research of mathematics besides the research by babies of Catholic. Of the persons charitably credited with playing a role in the history of mathematics during the Dark Ages, we might mention the martyred Roman citizen Boethius, the British ecclesiastical scholars Bede and Alcuin, and the famous French scholar and churchman Gerbert, who became Pope Sylvester π±. The work of Boethius about arithmetic and geometry had been used as a test book during many centuries. Gerbert was known to spread Indian - Arabic number without 0 to Europe and also he was known to make an abacus, a terrestrial globe, a celestial globe and watch and establish the first school at France in Europe. After that time, mathematics in Europe started to progress in the end of the middle age and the early part of the Renaissance (1100's-1400's).  The knowledge in this times was based on not Greek but Islam mathematics. Arabic mathematics played an important part Greece (and India) with modern Europe.

Europe in 1100's was the times of translation.   The superior publication of Greek and Arabic mathematicians, Archimedes, Apollonius, Ptolemy, Menelaus and Al-Khwarizmi translated to Latin in Arabia.

Fibonacci and The 13th Century:   In the early part of 1200's Leonardo Fibonacci, the most talented mathematician in middle age, came on the stage.
He was a man reconstructed mathematics of the middle age.   He was interested in arithmetic in childhood influenced by his father, and he traveled Egypt, Sicily, Greece, Syria and had a chance to meet east and Arabic mathematics. Finally he came back home in 1202 and published the famous Liber abaci. Liber abaci shows to be influenced by algebra of Al-Khwarizmi and Abu Kamil. This book played an important part to introduce Indian - Arabic number to Europe, and had many problems.  In this book, the following sequence is called Fibonacci's sequence.

1, 1, 2, 3, 5,...., x, y, x + y,.....

The Antagonism of Commercial Against Monastic Mathematics :
Though Indian-Arabic a system of measuring by decimal notation spread among the merchants, mathematicians persevere in Roman a system of measuring against Indian - Arabic a system of measuring. They were churchmen.
From this times the antagonism of progress against conservativeness appeared.
This antagonism has been known the fight between the abacuses and the algorisms.  The continuance of the antagonism proved that the algorisms won finally but they waited until 1500's. The characteristic of the algorisms was not only to calculus using 0 as a number without Indian - Arabic numeration system but also not to use abacus.   At last, Indian calculation spread abroad become of the progress of commerce and industry con fronted by the period of prosperity. Italy and Spain in 1400's and England, France and Germany in 17c used Indian - Arabic mathematics instead of Roman's.

The greatest mathematician in 1300's was Nicole Oresme born at Normandy in 1323. He was a professor and became a bishop and died in 1382.
One of the books he wrote used a fraction and an exponent for the first time (not modern expression), the other expressed coordinates as a point. It became the origin of modern coordinates geometry.
This paper in the end of 1300's influenced Descartes and many Penessance mathematicians. Luca Pacioli(1445 - 1509), a baby in Italy, wrote. This book contains many examples and commercial mathematics, especially bookkeeping by double entry.

Non-European Mathematics

We need to look over mathematics Arabia and India before moving to Middle and Modern Ages. That's why the two countries contributed to the development of the European middle ages mathematics.

Indian Mathematics: Greek mathematicians were good at geometry but they were not at arithmetic and algebra because they didn't use signs.
But Indian mathematises actively used symbols and they made Indo-Arabian numbers.  They also used decimal system. Indian mathematicians thought about the negative numbers for the first time and they made it a rule.
For example, Brahmagupta divided numbers into two: property (positive number) and debt (negative number).   But he didn't actually deal with 'negative numbers' freely as 'positive numbers.' He maybe thought that he could use 'negative numbers' in logical system not in practical.
Bhaskara even said that 'negative numbers' were unable-to-get-acquainted friends.  But, surprisingly.  Indo-Arabian numbers were as quite complete as people in other countries never dreamed it. The reasons why this kind of numbers were made and the art of calculation are as follows:

(1) They used very convenient tools for calculation (Indians wrote numbers on a small blackboard with bamboo pen and white ink)
(2) It may sound paradoxical, but they didn't know how to distinguish number from quality.
(3) Commerce developed in India earlier than other countries so they needed the art of calculation.

Although their achievements, they exposed some faults.
Mathematics was for the nobilities so it tended to be games they, specially, expressed mathematics in the form of verse, which brought about despising the strict demonstration and inference. Written by Bhaskara is a good example.  The name of the book is his daughter's.  It contained many meaningful contents but it is better known as a representative Sanskrit literary works. It was Arabian who developed Indian mathematics' merit. The field of algebra (equation) out of Europe-centered mathematics developed only in non-European countries. It were Europeans who used this Indo-Arabian mathematics but it developed so lively in Gupta Dynasty which had a great power in military, politics and culture from 4th to 12th century.

Arabian Mathematics: Arabians ruled parts of North Africa and Europe for 400 years since Mahomet (570~632).  They had new mathematics which was mixed Greek and Indian mathematics, which made Islam lead an important role in mathematics. Islamic mathematics, thus, became the starting point of modern European mathematics. When a slave state, Saracen Empire, was formed, commerce and trade developed. People needed convenient and accurate art of calculation. Accurate maps were needed to Arabian merchant.   Islamic ceremony (praying toward Mecca) had a great influence on the Arabian mathematics. Arabian merchants introduced Indian arithmetic and algebra into their commerce. On recent of Greek study, Arabians praised it so much and they translated many Greek classics in Greek.
Finally, Arabians fused Greek logical geometry Indian arithmetic and algebra and they renewed them. Without Arabians' effort to preserve and study the Greek culture, important Greek achievements about mathematics would disappeared.   Arabian mathematics, thus, had a great role in the history of mathematics.
Most people dealing with mathematics Arabia were astronomers because commerce, administration, measurement, the way of making maps, astronomy and the calendar method were needed to calculate and survey the area of a land. So we can say that mathematics in Arabia served as a setoff for astronomy as in China and India. Al-Khwarizmi was the most famous Arabian mathematician.
He wrote two books about algebra and Indian numbers.    When the two books were translated in Latin in 12th century, Europeans were quite influenced.
'Algorithm' today named after him means a certain process of calculation.
