Correction of the Wrong Answer

Assuming the problem was: Calculate (5 + 3 \times 2) and the student’s wrong answer was (16):

The student’s answer is incorrect.

Correct Answer

The correct result is (11).

Detailed Explanation

The mistake occurred because the student ignored the order of operations (PEMDAS/BODMAS rule), which dictates the sequence of calculations:

1. Parentheses/Brackets first,
2. Exponents/Orders next,
3. Multiplication and Division (left to right),
4. Addition and Subtraction (left to right).

For the problem (5 + 3 \times 2):

• Step 1: Perform multiplication first: (3 \times 2 = 6).
• Step 2: Then perform addition: (5 + 6 = 11).

The student incorrectly added (5 + 3 = 8) first, then multiplied by (2) to get (16), which violates the order of operations.

(\boxed{11})
