Aryabhata was the first of the major mathematician-astronomers who introduced the thought of using zero as a number instead of a placeholder and "created the concept of zero". Indian mathematician Brahmagupta extended his work with zero by establishing rules for it and formalizing it as a number. Brahmagupta said a number added to or subtracted from zero does not change the number. He also said that any number multiplied by zero equals zero and that zero divided by any number is zero

The Hindu-Arabic number system aka the decimal system is a (base-ten) system using the ten symbols 0-9 to represent numbers. Mathematicians from India helped create it by making the Brahmi numerals. The Brahmi numerals are a precursor to the hindu arabic number system.

Mathematics had a huge impact on ancient India by driving advancements in various fields. It helped in developing accurate astronomical models and calendars, which were crucial for agriculture and religious events. Indian mathematicians also made the concept of zero the modern decimal system and many other advancements in trigonometry and geometry. 

Mathematics had a lot of impacts on every civilization mathematics is the universal language it had impacts everywhere in almost every civilization. Some of the impacts include advancements in agriculture architecture, astronomy and daily life. The advancements in mathematics made by Indian mathematicians were passed along through trade routes.
