BASIC CONCEPTS : Whole Numbers and Natural Numbers------------------------------------------------------------------------------------------------------------------------ # Natural Numbers ALL the POSITIVE COUNTING NUMBERS starting FROM ONE are called Natural Numbers. We start counting from 1, 2, 3, 4, 5, … all these numbers which we use for COUNTING, are called Natural numbers.  # Whole Numbers Whole numbers are the COLLECTION OF NATURAL NUMBERS INCLUDING ZERO. So, the ZERO is the predecessor of 1 in the whole numbers. Whole numbers = 0 and Natural numbers means Whole numbers = 0 and 1, 2, 3, 4, 5 … 
BASIC CONCEPTS : Predecessor and Successor------------------------------------------------------------------------------------------------------------------------ # Successor - If we add 1 to any natural number, we get the next number, which is called the Successor of that number. We ADD +1 (plus 1) to any natural number => we get NEXT number Example: 14 + 1 = 15 So, 15 is the successor of 14. # Predecessor - If we subtract 1 from any natural number, we get the predecessor of that number. We SUBTRACT -1 (minus 1) from any natural number => we get the PREVIOUS number Example: 20 – 1 = 19 So, 19 is the predecessor of 20. #Note: There is no predecessor of 1 in NATURAL numbers. But, the ZERO is the predecessor of 1 in the WHOLE numbers. . |
