2. Subtract the rounded numbers: 900 - 600 = 300.
3. Subtract the rounded number from the original numbers:
- For 10,656: Subtract 300 from 10,656.
10,656 - 300 = 10,356.
- For 3,967: Subtract 300 from 3,967.
3,967 - 300 = 3,667.
4. Subtract the rounded numbers from the adjusted numbers:
- For 10,356: Subtract 600 from 10,356.
10,356 - 600 = 9,756.
- For 3,667: Subtract 967 from 3,667.
3,667 - 967 = 2,700.
5. Subtract the remaining numbers:
9,756 - 2,700 = 7,056.
Therefore, the value of the expression 10,656 - 3,967 (with adjustment) is 7,056.
