What is 81 - 34?

• A. 45
• B. 47
• C. 49
• D. 52

Answer: (B)

To solve the problem of subtracting 34 from 81, you start by aligning the numbers for clarity: ``` 81 - 34 ____ ``` Start with the digits in the units place. Subtract 4 (from 34) from 1 (from 81). Since 1 is smaller than 4, you must borrow 1 from the next column (the tens column). This makes the 8 in the tens place a 7 and changes the 1 to 11. Now, you can subtract: 11 - 4 = 7. Next, move to the tens place where you now have 7 (after borrowing). Subtract 3 from 7: 7 - 3 = 4. Putting it all together, you have: ``` 81 - 34 ____ 47 ``` Thus, the result of 81 - 34 is 47, confirming that the correct answer is indeed 47.
