Complete the following equation: 2 + (2)(2) - 2 ÷ 2 = ?

The correct answer is: 5

To solve the equation $ 2 + (2)(2) - 2 \div 2 $, it's 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)). 1. Evaluate the multiplication and division first: - The term $ (2)(2) $ equals 4. - The term $ 2 \div 2 $ equals 1. 2. Substitute these values back into the equation: - The equation now reads $ 2 + 4 - 1 $. 3. Next, perform the addition and subtraction from left to right: - First, add $ 2 + 4 $ to get 6. - Then, subtract $ 1 $ from 6 to obtain 5. Therefore, the correct answer to the equation is 5. The calculations demonstrate a straightforward application of the order of operations, leading to the final result.
