The Numbers are the basic units of processing to be done in mathematics. Numbers are taken as input in different procedures of mathematical operations and their output produced on the other side is also a number. Numbers are used for counting and measurement purposes in different areas.

Numbers which are used for counting are called natural Numbers. The smallest natural number is 1 and we go on adding 1 to get the series of natural numbers. So we see that adding 1 to 1 gives 2. Adding 1 to 2 gives 3, similarly this series goes on and does not end anywhere. So we can say that the series of natural numbers start from 1 and does not end anywhere.

According to natural numbers definition, we Mean that the counting numbers are natural numbers. When we think of counting anything, it may be apples in the basket, students present in the class or even the pens in the pencil box, we always start with a number 1, and so are the natural numbers. The natural number 1 is the smallest number and it goes on increasing to 2, 3, 4, 5,.. … up to infinite.

Natural numbers are endless and countless, there is no end to it, and every natural number is followed by the next number, which we get by adding 1 to it. So we say that the natural numbers starts with 1 and goes up to infinite. We must know that all the mathematical operators can be performed on the natural numbers and each natural number has a predecessor except 1, since 1 is the smallest natural number so we cannot subtract 1 from the smallest natural number.

All mathematical operators can be performed on the natural numbers namely addition, subtraction, multiplication and division. It means we can simplify the expression formed by the above four operators. Also we should know that the sum and the product of the two natural numbers is always a natural number, on another hand it is not always true for subtraction and division of natural numbers.
