Comparing numbers
Numbers are compared to check which one is higher/smaller than the others. Following things are checked to know that a number is greater or smaller:
If the number of digits in the numbers are different. The number having more digits is greater and the other is smaller.
If the number of digits is equal then the digit at the highestplace is compared.
Problem: Find the greatest and smallest numbers.
Solution: The green and yellow marked digits are qualifying digits for greatest and smallest numbers respectively. When number of digits are equal, then digits at ten thousands, thousands etc are compared until we get a highest and lowest digit. When number of digits is unequal, the number having more digits than all others is greatest and the number having lowest number of digits than all others is smallest.
