To efficiently subtract multi-digit numbers:
1. **Align the Numbers**: Write the numbers vertically, aligning them by their place values (units, tens, hundreds, etc.).
2. **Subtract Right to Left**: Start from the rightmost digit and move left, borrowing from the next higher place as needed.
3. **Borrow Correctly**: If the top digit is smaller than the bottom digit, borrow 1 from the next column over, adding 10 to the current digit.
4. **Write the Result**: After subtracting each column, write down the results directly below.
5. **Double-Check**: Review the calculations to ensure accuracy.
Practice helps improve speed and efficiency!
