Explanation

To solve the expression `357 xx 7 - 3 + 53 - 10` with the given meanings for the operations, we first need to replace the operations according to the rules provided:

1. **Replace the operations:**
- `-` means `+`
- `xx` means `div`
- `div` means `xx`
- `+` means `-`

Therefore, the expression `357 xx 7 - 3 + 53 - 10` becomes:
- `357 div 7 + 3 - 53 + 10`

2. **Now, rewrite the expression:**
- This translates to `357 div 7 + 3 - 53 + 10`.

3. **Perform the division first:**
- Calculate `357 div 7`:
\[ 357 \div 7 = 51 \]

4. **Substitute this value back into the expression:**
- Now we have:
\[ 51 + 3 - 53 + 10 \]

5. **Perform the addition and subtraction from left to right:**
- First, calculate `51 + 3`:
\[ 51 + 3 = 54 \]
- Next, calculate `54 - 53`:
\[ 54 - 53 = 1 \]
- Finally, calculate `1 + 10`:
\[ 1 + 10 = 11 \]

6. **Final Result:**
- The final answer is:
\[ 11 \]

Thus, the answer to the expression `357 xx 7 - 3 + 53 - 10` is **11**.
