Simplify: 54 + 6 × 3 − 45 ÷ 5
A. 81
B. 171
C. 27
D. 63✓ Correct Answer
💡 Solution & Explanation
Follow BODMAS: division and multiplication come before addition and subtraction. First 45 ÷ 5 = 9 and 6 × 3 = 18. Then 54 + 18 − 9 = 63. Working simply from left to right would give the wrong value, because it adds 54 and 6 before multiplying.
