**Quote:**"

**As the sun eclipses the stars by its brilliancy, so the man of knowledge will eclipse the fame of others in assemblies of the people if he proposes algebraic problems, and still more if he solves them." ~Brahmagupta**

Brahmagupta, 598 A.D. – 670 A.D., was an Indian
mathematician and astronomer. He is
credited for many significant contributions to mathematics and he authored many
textbooks for math and astronomy. One of
his most important works was the

*Brahmasphutasiddhanta*. In this book, Brahmagupta discredits many fellow mathematicians, finding fault in their theories. More importantly, he wrote about zero as a number rather than simply a placeholder. This idea of zero as a number has had far reaching implications for math as we know it today. Brahmagupta explains the addition and multiplicative properties of zero, as well as the rules for zero in terms of debts and fortunes (which we now know as positive and negative numbers). He also attempts to describe zero as a divisor, claiming that zero divided by zero is zero, which theory has since been challenged. Some mathematicians argue that n/0 is infinite, while others claim that the answer is one, infinity, or what we now term undefined. Some of Brahmagupta’s other major contributions to mathematics included algorithms for multiplication, square roots, quadratic equations, sums of powers of numbers, and computing sines, along with the formula for cyclic quadrilaterals (known as Brahmagupta’s Theorem). As an interesting side note, Brahmagupta also claimed that the world was round and not flat, which we now know to be true.**Read about Brahmagupta's Identity**known as Fibonacci's Identity
