PL HELP How did the Hindu-Arabic number system help mathematicians and scientists? It allowed them to calculate angles and curves.

It made calculations much easier than the Roman number system.

It provided a method for writing long equations.

It created a universal number system that people used all over the world.

The answer is that it made calculations much easier than the Roman number system.

Explanation:

Hindu-Arabic numerals, set of 10 symbols- 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 - that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians about the 12th century. They represented a profound break with previous methods of counting, such as the abacus, and paved the way for the development of algebra.

The Hindu-Arabic numerals, as they are now known, greatly facilitated arithmetic computations, particularly multiplication and division. They also allowed more rapid calculation of the mathematical tables needed for surveying, navigation, and the keeping of financial records and thus contributed to the extensive exploration and the growth of capitalism that characterized the Renaissance.

The system became known in western Europe through the works of Islamic commentators whose works were translated into Latin. The Hindu-Arabic numerals, as they are now known, greatly facilitated arithmetic computations, particularly multiplication and division.
