According to the BODMAS rule, division and multiplication are performed before addition and subtraction and are evaluated from left to right. Starting with 18 ÷ 3, we get 6, then multiplying 6 × 2 gives 12. The expression now becomes 12 + 12 − 4. Next, we perform addition and subtraction from left to right: 12 + 12 = 24 and then 24 − 4 = 20. Thus, the value of the expression is 20.
Option A:
Option A, 16, might result from an incorrect grouping of operations, such as performing addition or subtraction too early, but it does not respect the proper order dictated by BODMAS.
Option B:
Option B, 18, could arise from partial simplification without completing all operations in the correct sequence, but it fails to match the fully evaluated expression.
Option C:
Option C consistently applies the order of operations, handling division and multiplication first, then addition and subtraction. This careful sequencing leads to the accurate result of 20.
Option D:
Option D, 22, again does not correspond to the correct application of BODMAS and suggests an arithmetic error in combining the intermediate results.
