Show answer & explanation
Correct answer: B
Concept: BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) fixes the order in which the operations in an arithmetic expression must be carried out: resolve any brackets first, then powers or roots, then all division and multiplication reading left to right, and only after that all addition and subtraction reading left to right.
Application — apply the rule to this expression:
Write down the expression: 8 + 8 ÷ 4 + 8 × 2 − 4.
There are no brackets or powers, so scan left to right for division and multiplication first: 8 ÷ 4 = 2.
Continue the division/multiplication pass: 8 × 2 = 16.
Substitute both results back into the expression: 8 + 2 + 16 − 4.
Now perform the addition and subtraction left to right: 8 + 2 = 10.
10 + 16 = 26.
26 − 4 = 22.
Cross-check by grouping the same four terms differently: (8 + 16) + (2 − 4) = 24 + (−2) = 22 — the same result, confirming the value.
