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.
Numbers can be grouped into sets, called number systems. The following is a list of various number systems. Natural numbers: Natural number set consists of all counting numbers started with 1.(e.g. 1, 2, 3, â¦). Integers: Set of integers includes all natural numbers with zero and all negative numbers. A number, which produces zero when it is added to a positive number, is called the negative of that positive number. Real numbers: Real numbers consist of all the measuring numbers.
