Final answer:
The numerical system we use was developed by Indian mathematicians during the Gupta period, though it is commonly referred to as Arabic numerals in the West.
Step-by-step explanation:
The numbering system we use today originated in India during the Gupta period, which is considered a time of significant advances in Indian mathematics.
Although these numbers are called Arabic numerals in the West due to the transmission of this knowledge through Arab scholars, the system itself, including the concept of zero and the place value system, was developed by Indian mathematicians. Notable Indian scholars like Brahmagupta played a crucial role in pioneering the use of multiplication, division, and negative numbers.
