What is the value of 15 - (3 × 4)?

  1. 3

  2. 7

  3. 9

  4. 12

The correct answer is: 9

To find the value of the expression 15 - (3 × 4), it is essential to follow 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 resolve the operation inside the parentheses. In this case, we multiply 3 by 4, which gives us 12. Next, we substitute this value back into the expression, so it becomes 15 - 12. Finally, we perform the subtraction: 15 minus 12 equals 3. Thus, the correct value for the expression 15 - (3 × 4) is 3.
