By the 7th century, Indian mathematicians such as Brahmagupta were describing the use of negative numbers. Islamic mathematicians further developed the rules of subtracting and multiplying negative numbers and solved problems with negative coefficients.
How did negative numbers come about?
The first mention of negative numbers can be traced to the Chinese in 200 B.C.E. The Chinese used red rods to represent positive numbers, but black rods to represent negative numbers. In the fourth century, the Alexandrian mathematician Diophantus said in his text Arithmetica that the following equation is absurd.
Who invented positive and negative numbers?
The Indian mathematician Brahmagupta (597-667 CE) appears to be the first to articulate the result that the product of two negative numbers is a positive number. He of course also gave the much easier result that the product of a positive number and a negative number is a negative number.
