WHOLE NUMBERS
If we would like to describe the ‘Whole Numbers’ in a single ward then we can say that, all natural numbers together starting with 0 (Zero) are called whole numbers. You will be pleased to know that, the collection of all whole numbers is called the set of all whole numbers and it is denoted by ‘W’.
Thus W = 0, 1, 2, 3, 4, 5, 6, 7, 8 , 9 , 10 , 11 , 12 , 13 , 14, 15……………….and so on
