Finding Out the Numbers

Finding out the numbers possible with 1-digit, 2-digit, 3-digit, etc,.

(a) The smallest 1-digit number is 1.

The greatest 1-digit number is 9.

Therefore, 9 - 1 = 8 and 8 + 1 = 9

So, we say that we have 9 one-digit numbers.


(b) The smallest 2-digit number =10.

The greatest 2-digit number = 99.

Therefore 99 - 10 = 89 and 89 + 1 = 90

So, we say that we have 90 two-digit numbers.


(c) The smallest 3-digit number = 100.

The greatest 3-digit number = 999.

There for 999 - 100 = 899 and 899 + 1 = 900

So, we say that we have 900 three-digit numbers. 

(d) The smallest 4-digit number = 1000. 

The greatest 4-digit number = 9999. 

There for 9999 - 1000 = 8999 and 8999 + 1 = 9000 

So, we say that we have 9000 four-digit numbers. 



We observe a pattern in this:

1-digit number = 9

2-digit numbers = 90

3-digit numbers = 900 

4-digit numbers = 9000 

Therefore, in finding out the numbers we can say 5-digit numbers = 90000 and so on…..
