Let's work through the subtraction problems step by step and show the detailed process for each.

---

### c. \( 236 - 174 \)

We solve this by subtracting column by column:

1. **Ones column:**  
   \( 6 - 4 = 2 \)
   
2. **Tens column:**  
   \( 3 - 7 \) → we need to borrow 1 from the hundreds column.  
   \( 13 - 7 = 6 \)
   
3. **Hundreds column:**  
   \( 1 - 1 = 0 \) (after borrowing)

So,  
**\( 236 - 174 = 62 \)**

---

### d. \( 677 - 468 \)

1. **Ones column:**  
   \( 7 - 8 \) → borrow from the tens column.  
   \( 17 - 8 = 9 \)
   
2. **Tens column:**  
   \( 6 - 6 = 0 \)
   
3. **Hundreds column:**  
   \( 6 - 4 = 2 \)

So,  
**\( 677 - 468 = 209 \)**

---

### e. \( 467 - 393 \)

1. **Ones column:**  
   \( 7 - 3 = 4 \)
   
2. **Tens column:**  
   \( 6 - 9 \) → borrow from the hundreds column.  
   \( 16 - 9 = 7 \)
   
3. **Hundreds column:**  
   \( 3 - 3 = 0 \) (after borrowing)

So,  
**\( 467 - 393 = 74 \)**

---

### g. \( 903 - 520 \)

1. **Ones column:**  
   \( 3 - 0 = 3 \)
   
2. **Tens column:**  
   \( 0 - 2 \) → borrow from the hundreds column.  
   \( 10 - 2 = 8 \)
   
3. **Hundreds column:**  
   \( 8 - 5 = 3 \) (after borrowing)

So,  
**\( 903 - 520 = 383 \)**

---

### h. \( 654 - 361 \)

1. **Ones column:**  
   \( 4 - 1 = 3 \)
   
2. **Tens column:**  
   \( 5 - 6 \) → borrow from the hundreds column.  
   \( 15 - 6 = 9 \)
   
3. **Hundreds column:**  
   \( 5 - 3 = 2 \) (after borrowing)

So,  
**\( 654 - 361 = 293 \)**

These are the steps showing all the borrowing and subtractions for each problem. Let me know if you'd like more details or clarifications!

Here are 5 follow-up questions:
1. Can you explain how borrowing works when subtracting larger digits from smaller ones?
2. How can subtraction problems with borrowing be checked for correctness?
3. What strategies help avoid errors in multi-digit subtraction?
4. Could subtraction in different number bases (like base-8 or base-16) change the borrowing method?
5. How does mental math subtraction differ from written subtraction with borrowing?

**Tip:** Always double-check subtraction by adding the result to the subtrahend (the number being subtracted) to see if you get back to the original number!
