#Making numbers
Suppose we have 4 digits 7, 8, 3, 5. We want to make different 4-digit numbers using these digits such that no digits are repeated in each number. For example, you can make 7835 and 3578 but 7738 is not allowed because 7 is repeated and 5 is not used.
a. What is the greatest number you can make?
b. What is the smallest number?
c. Can you write down how you make the greatest number and the smallest number?
Use the given digits without repetition and make the greatest and smallest 4-digit numbers. Note that 0753 is a 3 digit number and is therefore not allowed.

#Now make the greatest and smallest 4-digit numbers by using any one digit twice.
Hint: Think about which digit you will use twice.
