Explanation:

Step1: Analyze the subtraction operation

We know that \( 754 - 379=\text{result} \). Let's perform the subtraction digit by digit.

• Units place: \( 4 - 9 \), we need to borrow 1 from the tens place. So \( 14 - 9 = 5 \).
• Tens place: After borrowing, the 5 in the tens place becomes 4. Now \( 4 - 7 \), we need to borrow 1 from the hundreds place. So \( 14 - 7 = 7 \).
• Hundreds place: After borrowing, the 7 in the hundreds place becomes 6. Now \( 6 - 3 = 3 \).

Step2: Verify the subtraction

\( 754-379 = 375 \)? Wait, no, wait. Wait, let's do the subtraction correctly:
\( 754 - 379 \):

• Units: \( 4-9 \), can't do, borrow 1 from tens, so 14 - 9 = 5. Tens place: 5 becomes 4 (after borrowing 1), now 4 - 7, can't do, borrow 1 from hundreds, so 14 - 7 = 7. Hundreds place: 7 becomes 6 (after borrowing 1), 6 - 3 = 3. So \( 754 - 379=375 \)? Wait, no, 379 + 375 = 754? Let's check: 379+375: 9+5=14, 7+7 +1=15, 3+3+1=7. So 379+375=754. Wait, but the problem is \( 754 - 379 \), so the result is 375? Wait, the boxes are three digits. Wait, the first box (hundreds), second (tens), third (units). So the result of \( 754 - 379 \) is 375. Wait, but let's re - calculate:

\( 754-379 \):

Hundreds: 7 - 3 = 4? No, wait, we have to consider borrowing. Let's do it step by step:

1. Units digit: 4 - 9. Since 4 < 9, we borrow 1 from the tens digit. The tens digit is 5, so we make it 4 (after borrowing 1), and the units digit becomes 14. Then \( 14 - 9=5 \).

1. Tens digit: Now we have 4 (after borrowing 1 from the tens place earlier) and we need to subtract 7. Since 4 < 7, we borrow 1 from the hundreds digit. The hundreds digit is 7, so we make it 6 (after borrowing 1), and the tens digit becomes 14. Then \( 14 - 7 = 7 \).

1. Hundreds digit: Now we have 6 (after borrowing 1 from the hundreds place) and we subtract 3. So \( 6-3 = 3 \).

So putting it all together, \( 754 - 379=375 \). Wait, but the problem's subtraction is \( 754-379 \), so the missing digits are 3 (hundreds), 7 (tens), 5 (units)? Wait, no, wait the problem is written as:

\(

$$\begin{array}{r} 754\\ -379\\ \hline \square\square\square \end{array}$$

\)

So we need to find \( 754 - 379 \). Let's compute:

\( 754-379=(700 - 300)+(50 - 70)+(4 - 9)=400-20 - 5 = 375 \).

Answer:

3, 7, 5 (the three digits from top to bottom in the boxes)
