Answer 3

Let's simplify the expression step by step:

7 + (-8) - (-12) - (-7) + 12 - 20

First, let's simplify the double negatives:

7 + (-8) + 12 + 7 + 12 - 20

Now, let's add and subtract the numbers:

(7 + 12 + 7 + 12) + (-8 - 20) 38 + (-28)

Now, add the positive and negative numbers:

38 - 28

Finally, subtract 28 from 38:

38 - 28 = 10

So, the simplified result of the expression is 10.
