Zero is an even number, because it is divisible by 2 with no remainder. 0 is neither positive nor negative. By most definitions 0 is a natural number, and then the only natural number not to be positive. Zero is a number which quantifies a count or an amount of null size. In most cultures, 0 was identified before the idea of negative things, or quantities less than zero, was accepted. The value, or number, zero is not the same as the digit zero, used in numeral systems using positional notation.
1, 2, 3, 4, and so on, are the familiar numerals for the natural numbers. We calculate with those symbols, and so it has become conventional to call the symbols themselves numbers.. Yet a symbol is not what it symbolizes, what it stands for, which in this case is a number of discrete units.e say however that a number is a divisor of itself. With the exception of the number itself, the divisors of a number are the only parts that a number has. 3 is the fourth part of 12. 5 is not any part of 12; you cannot divide 12 people into groups of 5.
