The expression that calculates to 10 is:
(2 * 6) - 2 / 2
Let's break it down step by step:
1. First, calculate the multiplication inside the parentheses: 2 * 6 = 12.
2. Then, subtract 2 from the result: 12 - 2 = 10.
3. Finally, divide the result by 2: 10 / 2 = 5.
So, the expression (2 * 6) - 2 / 2 equals 5, not 10.
