Although the first set of rules for dealing with negative numbers was stated in the 7th century by the Indian mathematician Brahmagupta, it is surprising that in the British mathematician Francis Maseres was claiming that negative numbers " In BCE the Chinese number rod system see note1 below represented positive numbers in Red and Negative numbers in black. An article describing this system can be found here.
These were used for commercial and tax calculations where the black cancelled out the red. The amount sold was positive because of receiving money and the amount spent in purchasing something was negative because of paying out ; so a money balance was positive, and a deficit negative. A debt minus zero is a debt. A fortune minus zero is a fortune. Zero minus zero is a zero. A debt subtracted from zero is a fortune. A fortune subtracted from zero is a debt. However, history teaches us that the concept of negative numbers was not embraced wholeheartedly by mathematicians until somewhere around the 17th century.
