The school bell rings once in an hour, to indicate that the session ends/next session begins. And for break, it will be 20 minutes. Shall we try to fill this up?

| Multiply it by 9 | ×9 |
| Total | 99 |
Now you choose any 3 × 3 boxes from a calendar and find the total in the same way.
Now try doing it with some other number and also take a different number to add at each step.
