1.2.1 How many numbers can you make?

Suppose, we have four digits 7, 8, 3, 5. 

Using these digits we want to make different 4-digit numbers in such a way that no digit is repeated in them. 

Thus, 7835 is allowed, but 7735 is not. 

Make as many 4-digit numbers as you can. 

Which is the greatest number you can get? Which is the smallest number? 

The greatest number is 8753 and 

the smallest is 3578. 

but 7735 is not. 7735 BE ALLOWED 

BECAUSE WE CAN WRITE BIG TO SMALL  7,7,3,5

SMALL TO BIG   3,5,7,7

Think about the arrangement of the digits in both. Can you say how the largest number is formed? Write down your procedure.
