In this video Mayank discusses the rules for arranging numbers in ascending (increasing) or descending (decreasing) order. The idea is to compare the digits starting from most significant one.
This class also covers how to make smallest and largest numbers using given digits.
Finally we discuss now to form new numbers by shifting digits of existing numbers
Questions:
1. Arrange: 1473, 89423, 100, 5000, 310
2. Arrange: 15623, 15073, 15189, 15800
3. Find the largest possible 3 digit number using 9, 3, 4
4. Find the smallest possible 3 digit number using 0, 3, 9
5. Make the greatest and the smallest 4-digit numbers using any four different digits with digit 9 in once place
