? In order to compare two numbers, we adopt the following 
rulers:-
RULE 1:- The number with less digits is less than the number with 
more digits.
RULE 2:- Suppose we have to compare two numbers having the 
same numbers of digits than we proceed as under
Step 1- First compare the digits at the leftmost place in both the 
numbers.
Step 2- If they are equal in value then compare the second digits 
from the left.
Step 3- if the second digits from the left are equal then compare the 
third digits from the left.
Step 4- continue until you come across unequal digits at the 
corresponding places. Clearly, the number with greater such 
digit is the greater of the two.
