“This fraction of which the denominator is a cipher, is termed an infinite quantity,” writes Bhaskara, a twelfth-century Indian mathematician, who tells of what happens when you add a number to 1 + 0.

The Indian mathematician Bhaskara wrote in the twelfth century that “there is no square root of a negative number, for a negative number is not a square.”

What Bhaskara and others realized was that when you square a positive number, you get a positive number back; 2 times 2 equals 4, for instance.
