Natural numbers are naturally used for counting apples (and other things) so they are sometimes called counting numbers. Even some animals other than humans can count and add, so they must be natural. Minus two apples isn't very natural so negative numbers are not included.
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.
