What is the result of simplifying the expression: 14 - (2 + 2 x 5)?

A. 2
B. 4
C. 6
D. 10

The correct answer is: A. 2

To simplify the expression 14 - (2 + 2 x 5), it's important 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, resolve the operations inside the parentheses: - Within the parentheses, you have the expression 2 + 2 x 5. According to the order of operations, you should perform the multiplication first. - Calculate 2 x 5, which equals 10. - Then, add that result to 2: 2 + 10 = 12. Now, substitute that back into the initial expression: 14 - (2 + 10) simplifies to 14 - 12. Finally, perform the subtraction: 14 - 12 equals 2. Therefore, the result of simplifying the expression is 2.
