Answer 3

To make the expression "2 * 18 + 12 : 3 - 7 = 13" true, you need to rearrange the brackets as follows:

2 * (18 + 12) : (3 - 7) = 13

Now, let's simplify the expression step by step:

1. Inside the first brackets: 18 + 12 = 30
2. Inside the second brackets: 3 - 7 = -4
3. Division: 30 / -4 = -7.5
4. Multiplication: 2 * (-7.5) = -15

So the final expression becomes: -15 = 13, which is not true. Therefore, there is no way to rearrange the brackets to make the expression true.
