| + | #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. |
| + | |
| + | [[File:gretest and smallest.png|400px|link=]] |
| + | #Now make the greatest and smallest 4-digit numbers by using any one digit twice. |
| + | Hint: Think about which digit you will use twice. |
