The whole numbers are the counting numbers including 0.
All natural numbers along with 0 are called whole numbers. There are unlimited whole numbers starting with the smallest whole number 0.
We have seen that the numbers 1, 2, 3, 4, 5, 6………. etc. are naturalnumbers. These natural numbers along with the number zero from thecollection of whole numbers. The numbers 0, 1, 2, 3, 4, …………… are calledwhole numbers.
The smallest whole number is 0.
The first 100 whole numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25,26, 27, 28, 29, 30, 31, 32,33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70,71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89,90, 91, 92, 93, 94, 95, 96, 97, 98, 99.
Thus, a whole numbers is either 0 or a natural number.
I: Every natural number is a whole number.
II: Zero is the only number which is a whole number but not a natural number.
1. State True or False:
(i) Zero is the smallest natural number.
(ii) 1 is the smallest whole number.
(iii) All natural numbers are not whole numbers.
(iv) All whole numbers are natural numbers.
