Detailed explanation-1: -Excavations at Mohenjodaro, Harappa and the surrounding area of the Indus River discovered evidence of the use of basic mathematics. The mathematics used by the early Harappan civilization had mostly practical intent and was concerned with weights and measuring scales. Excavations present knowledge of basic geometry.

Detailed explanation-2: -As well as giving us the concept of zero, Indian mathematicians made seminal contributions to the study of trigonometry, algebra, arithmetic and negative numbers among other areas. Perhaps most significantly, the decimal system that we still employ worldwide today was first seen in India.

Detailed explanation-3: -The decimal number system in use today was first recorded in Indian mathematics. Indian mathematicians made early contributions to the study of the concept of zero as a number, negative numbers, arithmetic, and algebra.
