Whole Numbers

Whole Numbers The numbers used for counting are called natural numbers.

The numbers used for counting are called natural numbers.  The number that comes immediately before another number in counting is called its predecessor.  The number that comes immediately after another number in counting is called its successor.  To find the successor of any given natural number, just add 1 to the given number.  The value of nothing is represented by the number zero. 

 Eg: 3 – 3 = 0
Natural numbers together with the number zero are called whole numbers.  When comparing two whole numbers, the number that lies to the right on the number line is greater.  When comparing two whole numbers, the smaller number lies to the left on the number line.
