What is the value of the expression (3 + 4) × 2?

  1. 10

  2. 14

  3. 16

  4. 20

The correct answer is: 10

To determine the value of the expression (3 + 4) × 2, we start by following the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, we evaluate the expression inside the parentheses: 3 + 4 = 7. Next, we take the result and multiply it by 2: 7 × 2 = 14. Thus, the correct value of the expression (3 + 4) × 2 is 14. This means that the answer selected does not match the correct calculation, indicating a misunderstanding that can be clarified by following the proper order of operations to avoid such errors in future calculations.
