Here are the Achievements of the Gupta Empire:
Invention of the Decimal System- The Arabic decimaml system uses the same 10 digits that we use today (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9). This number system was created by mathematician Al Khwarizmi between the 1st century and the 5th century.
Universities- The most famous university was the Buddhist school in Nalanda. This school had 8 collages and 3 libraries. It also had a hospital and monastery. Students there were taught Buddhist and Hindu philosophy. They also learned logic, grammar, and medicine.
Trade- The Gupta Empire traded with Thailand, Rome, Western Asia, China, Malaysia, Eastern Archipelago, and Cambodia. They traded Spices, Copper, and other goods.
Literature- Most of the literature was written in Sanskrit. This era is known for equal writing of prose and poetry. Yajnavalkyasmriti, which is almost regarded as the official law book of Guptas, was created in this era.
Metalwork- The pillar of Meharauli is a 25 foot tall solid iron pillar that weighs 6 and a half tons (13,000 pounds). After 1,600 years, this pillar still does not have any rust.
Roads- To make the roads they cleared plants, trees, and rock. Holes were filled in and
workers smoothed the ground until it was leveled, Then once they were done, the roads were made out of hard-packed dirt.
