Subtract 489 from 1000 using the base method. What is the result?a)521...
- To subtract 489 from 1000 using the base method, we transform the subtraction into a simpler form.
- Start with 1000, which is a round number.
- Apply the "All from 9 and the Last from 10" rule:
- From the rightmost digit (0), we need to take 9, so we borrow 1 from the next digit.
- This converts the 0 to 10 (after borrowing), making it 10 - 9 = 1.
- The next digit becomes 9 (due to borrowing), so 9 - 8 = 1.
- Finally, since we borrowed from the hundreds, we have 9 left from 10, so 10 - 4 = 5.
- Thus, 1000 - 489 = 511.

Understanding the Base Method Subtraction
To subtract 489 from 1000 using the base method, we can break down the process step by step.
Step 1: Identify the Base
- The base number here is 1000.
- We want to subtract 489 from it.
Step 2: Break Down the Subtraction
- We can think of 1000 as 1000 - 489.
- Instead of subtracting directly, we can subtract 490 first, as it is easier to manage.
Step 3: Perform the Subtraction
- Calculate 1000 - 490, which equals 510.
- Since we subtracted 1 more (490 instead of 489), we need to add that back to our result.
Step 4: Adjust the Result
- Add 1 back to 510:
- 510 + 1 = 511.
Final Result
- Therefore, 1000 - 489 equals 511.
Conclusion
- The correct answer is option 'B': 511.
- This method simplifies the calculation and helps avoid mistakes by breaking the problem into manageable parts.
