The correct option is 22.\nThe given expression is $30 - 6 \times 2 + 4$. According to the BODMAS/PEMDAS rule, multiplication should be performed before addition or subtraction.\n1. Perform multiplication: $6 \times 2 = 12$.\n2. The expression becomes: $30 - 12 + 4$.\n3. Now perform subtraction and addition from left to right: $30 - 12 = 18$.\n4. Finally, perform addition: $18 + 4 = 22$.\nThe student's answer of 52 results from performing operations from left to right without respecting the order of operations ($30 - 6 = 24$, then $24 \times 2 = 48$, then $48 + 4 = 52$). Option 14 would result from doing addition before subtraction ($30 - (12+4)$).
