WORLD HISTORY

Detailed explanation-1: -About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it ‘sifr’. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.

Detailed explanation-2: -By about 500 AD the classical era of Indian mathematics began with the work of Aryabhata. His work was both a summary of Jaina mathematics and the beginning of new era for astronomy and mathematics.

Detailed explanation-3: -Zero helps us understand and explain concepts that do not have physical forms! The number zero is used as a placeholder in the place value system. For example, two zeros before a number indicate a hundred position, while a single zero before a digit indicates a tens position.

Detailed explanation-4: -Indian mathematicians made early contributions to the study of the concept of zero as a number, negative numbers, arithmetic, and algebra. In addition, trigonometry was further advanced in India, and, in particular, the modern definitions of sine and cosine were developed there.
