📝 Explanation:

Since this is "Without Regrouping", we can subtract digit by digit from right to left, and no borrowing is needed because each digit in the minuend (top number) is larger than or equal to the corresponding digit in the subtrahend (bottom number).

For example:
- In 864 - 233:
- 4 - 3 = 1
- 6 - 3 = 3
- 8 - 2 = 6 → Result: 631

This method ensures that students practice place value understanding without the complexity of borrowing.
