Reduce 5 to 4 (one less than the one before). Apply the sutra to 76: 7 from 9 is 2, 6 from 10 is 4. Then, 500 - 76 = 400 + 24 = 424.

Understanding the Concept
To solve 500 - 76 using the "All from 9 and the Last from 10" method, we will break down the numbers involved.
Step 1: Subtract from 9
- For each digit in 76, we subtract it from 9.
- The first digit is 7: 9 - 7 = 2
- The second digit is 6: 9 - 6 = 3
Now, we have the digits 2 and 3.
Step 2: Apply "The Last from 10"
- Since the last digit of 76 is 6, we need to subtract 1 from 10 for the last part.
- 10 - 6 = 4
Now, we combine the results from Step 1 and Step 2.
Combining Results
- The first result was 2 and the second was 3, but we need the last digit to be 4 (from the last step).
- So we have 2 and 3, but since we are applying "One less than the one before," we need to adjust the numbers accordingly.
Now, we have:
- First digit becomes 4 (2 + 2)
- Second digit becomes 4 (3 + 1)
Final Calculation
Combining these, we get 424.
Thus, the answer to 500 - 76 is 424, which corresponds to option 'B'.
Conclusion
- The process simplifies subtraction by transforming the numbers.
- Using these methods, we can find the answer efficiently and accurately.
