(1) NATURAL NUMBER
A natural number is a number that occurs commonly and obviously in nature. As such, it is a whole, non-negative number. The set of natural numbers, denoted N, can be defined in either of two ways: N = {0, 1, 2, 3, ...} ... However, i is more often used to represent the positive square root of -1, the unit imaginary number.
(2) whole number
Whole numbers are positive numbers, including zero, without any decimal or fractional parts. They are numbers that represent whole things without pieces. The set of whole numbers is represented mathematically by the set: {0, 1, 2, 3, 4, 5...}.
(3)prime number
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole numbers that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Numbers that have more than two factors are called composite numbers.
(4) composite number
A whole number that can be made by multiplying other whole numbers. Example: 6 can be made by 2 × 3 so is a composite number. ... All whole numbers above 1 are either composite or prime.
