Brahmagupa Brahmagupta was
born in 598 A.D. and lived in the northwest of ax + by = c Brahmagupta has
developed a method of solving indeterminate equations of the second degree and
rules of solving simple quadratic equations of various types. The Brahma
Sidhanta is the earliest known text other than the Mayan
number system to treat zero as a number in its own right. It goes well
beyond that, however, stating rules for arithmetic on negative numbers and zero
which are quite close to the modern understanding. The major divergence is that
Brahmagupta attempted to define division
by zero, which is left undefined in modern mathematics. He states that 0/0
= 0, which would be a handicap to discussion of removable singularities (is a
point at which the function is not defined, but at which the function can be
defined without creating any problems) in calculus. Reference
