Read Explanation:
1. Substitute the letters with their respective signs:
$54 \div 9 \times 11 - 13 + 17$
2. Division (B):
$54 \div 9 = 6$
The equation becomes: $6 \times 11 - 13 + 17$
3. Multiplication (M):
$6 \times 11 = 66$
The equation becomes:
$66 - 13 + 17$
4. Addition and Subtraction (A & S):
Add the positive numbers first: $66 + 17 = 83$
Then subtract: $83 - 13 = \mathbf{70}$
