The numbers can be expressed in the following forms
Any natural number can be written in the expanded form by using the place values of its digits. For example:
1.
2.
Any natural number can be expressed in exponential form by using powers of 10 and the digits of the number . For example,
1.
2.
3.
The general form of writing any number is using the literals instead of numbers.Let us now consider a two digit number using literals a and b respectively as tens and units digits.
Using the above notations the number can be written both in expanded form or exponential form as follows:
Let us use the notation to denote this number.
i.e, or ,
Here, we have put a line over ab to distinguish it from the expression ab, which means a multiplied by b.
This is known as the generalised form of a two digit number.
The general form of writing any number is using the literals instead of numbers.Let us now consider a three digit number using literals a, b and c respectively as hundreds, tens and units digits.
Using the above notations the number can be written both in expanded form or exponential form as follows:
Let us use the notation to denote this number.
i.e, or ,
Here, we have put a line over abc to distinguish it from the expression abc, which means a multiplied by b and then multiplied by c.
This is known as the generalised form of a three digit number.
Illustration: What does the literal a in the general form represents for the number 365
Solution: While expressing 365 in expanded form we get
on comparing with the general form
we get a = 3.
Thus the literal a represents 3 in the general form
