The number zero that we are accustomed to, came into existence rather late, around 200 A.D. (centuries after the great Classical Greek Period, which can arguably be called the origin of the modern mathematics). The number zero as we know it was conceived by the Hindus from India. The Hindus were the first to recognize a mathematical representation of concept of no quantity. It had not occurred to earlier civilizations, even to the Greeks, that it would be useful to have a number which represents the absence of any objects.
Zero has long been philosophized about because the nature of nothing, or no-thing, is paradoxical in nature. Just as the nature of a Higher Power, zero is everywhere and no where at the same time. Here are some of the rules for how zero is used mathematically. Notice the same can be said for Consciousness.
- The sum of zero and a negative number is negative.
- The sum of zero and a positive number is positive.
- The sum of zero and zero is zero.
- The sum of a positive and a negative is their difference; or, if they are equal, zero.
- A positive or negative number when divided by zero is a fraction with the zero as denominator.
- Zero divided by a negative or positive number is either zero or is expressed as a fraction with zero as numerator and the finite quantity as denominator.
- Zero divided by zero is zero.
