Simplify: 25 + 4 × 5 − 10 ÷ 5
A. 143
B. 47
C. 43✓ Correct Answer
D. 27
💡 Solution & Explanation
Follow BODMAS: division and multiplication come before addition and subtraction. First 10 ÷ 5 = 2 and 4 × 5 = 20. Then 25 + 20 − 2 = 43. Working simply from left to right would give the wrong value, because it adds 25 and 4 before multiplying.
