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?
Here is the time table.
| Period 1 | Period 2 | Break | Period 3 | Period 4 | Break | Period 5 | Period 6 |
| 9:00 | 10:00 | 11:00 | 2:40 |
Look at the calendar below.
Let us mark 3 × 3 boxes (9 dates) on the calendar and see some magic.
| Take the smallest number | 3 |
| Add 8 to it | +8 |
| = | 11 |
| 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.
Take the first two odd numbers. Now add them, see what you get. Now, at every step, add the next odd number.|
How far can you go on?
