Also the decimal system that is used by the world today originated from India. These mathematical concepts where first transmitted to the middle East, China, Europe and later to all part of the world. It was spread orally and later through manuscripts.

Through manuscripts,other scientist were able to see it, develop and adopt India mathematical concepts though it took while before some scientist in Europe could accept it.

As people migrate then, manuscripts was spread to other parts of the world and mathematicians all round were able to see it.

It spread to manuscript via transportation.

Answer and Explanation:

Mathematics spread through Moorish universities in Spain and then traveled to European countries. Indian mathematics became the foundation of European mathematics.

Chinese used to have a smaller understanding of formal notational system then Indian notational system spread through Arabs.

In the 18th century, Indian scholars went to Baghdad, and they took books with them during the reign of the Khalif Al-Mansur. That is how Indian numerals reached Baghdad. Furthermore, it was the first systematic approach. Books like Aryabhata were translated into Arabic.

Indian numerals also have a significant rule in influencing astronomy in the Arab world.

Baghdad was also the Centre of learning. The translation of Indian mathematics into Arabic spread into the vast areas.
