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.
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.
