Show answer & explanation
Correct answer: B
Step 1: Replace each symbol with its given meaning.
Original expression: 56 − 8 × 5 ÷ 4 + 7
After substitution the expression becomes: 56 ÷ 8 − 5 + 4 × 7
Evaluate multiplication first: 4 × 7 = 28.
Evaluate division next: 56 ÷ 8 = 7.
Perform subtraction: 7 − 5 = 2.
Perform the final addition: 2 + 28 = 30.
