Is zero a positive integer?

Although zero is defined as an integer, it is neither positive nor negative. Zero is the integer interval between positive and negative numbers, where an integer is defined as a non-fractional number.

The number zero was historically developed after basic counting systems. The first known recorded use of a symbol for zero was in ancient Egypt. Hieroglyphic accounting texts dating to 1740 B.C. use the symbol "nfr," meaning "beautiful," for a symbolic placeholder digit. It wasn't until centuries later that Indian mathematicians developed the concept of zero as a number. The "Brahmasputha Siddhanta," or "Opening of the Universe," written by Brahmagupta in A.D. 628, lists the mathematical operations of zero in a series of rules.
