\( 2 \times(5+4)-3 \times 4 \) (A) 6 (B) 24 (C) 48 (D) 60

To solve the expression \( 2 \times(5+4)-3 \times 4 \), we start by calculating inside the parentheses: \( 5 + 4 = 9 \). Then, we multiply: \( 2 \times 9 = 18 \). Next, we calculate the second part: \( 3 \times 4 = 12 \). Now, we subtract: \( 18 - 12 = 6 \). So, the answer is (A) 6. This problem showcases the importance of following the order of operations, commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Getting the order right makes all the difference! Next time you tackle a math problem, remember that small errors in calculations can lead you astray! A common mistake is skipping parentheses, which can drastically change the outcome. Always double-check each step to ensure you arrive at the correct result.
