WORLD HISTORY

Detailed explanation-1: -In the seventh century, the first written evidence of the rules for working with zero were formalised in the Brahmasputha Siddhanta. In his seminal text, the astronomer Brahmagupta introduced rules for solving quadratic equations (so beloved of secondary school mathematics students) and for computing square roots.

Detailed explanation-2: -The invention of zero immensely simplified computations, freeing mathematicians to develop vital mathematical disciplines such as algebra and calculus, and eventually the basis for computers.

Detailed explanation-3: -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.

Detailed explanation-4: -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-5: -It was the Indian sages who first drew a symbol to represent zero, a digit that does not appear in Greek writings or among Roman numerals. That simple symbol granted mathematicians the ability to operate with numbers as large as they wanted.

Detailed explanation-6: -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.
