## Historical Note on Division by Zero

Brahmagupta stated that:

*positive or negative divided by cipher is a fraction with that for denominator*.

This was then referred to as **quantity with zero as denominator**.

Mahaviracharya writes in *Ganita Sara Samgraha* of c. $850$ CE:

*A number multiplied by zero is zero and that number remains unchanged which is divided by, added to or diminished by zero.*

which is of course seriously questionable.
