Let usthinkover‘WhoIam’–
- I am a 5 digit number.
- I am a number immediately preceding to the largest three digit number.
- The digit in my ten thousand’s positionis the difference of digits in my tenth and unit’s positions.
- The digit in my thousandth position represents the standard of my class.
Now write down ‘Who I am’ = 89958
Think and fill inthe blank spaces:
- Positional value of 9is 95072 in Ten thousand’s i.e 90,000.
- The least 4 digit number is 1000 and the greatest 4 digit number is 9999.
- The number preceding the least 4 digit numberis
- 4563+0=4563
- 10000–1000=9000.
- Adding 1 to the largest 4 digit number results in the least 5 digit number.
Let us think and write down the appropriate numbers to be inserted in the blank circles and squares–
1210 Can be addition of
- 905 + 305
- 1000 + 210
- 605 + 605
- 500 +710
