Answer 3

Let's simplify the expression step by step:

-2 * (-5) = 10 20 / (-2) = -10 10 * (-1) = -10

Now, let's rewrite the expression with the simplified values:

10 + (-10) - (-10) - 9

Now, simplify further:

10 + (-10) = 0

• (-10) = 10

Now, the expression becomes:

0 + 10 - 9

Now, simplify the remaining additions and subtractions:

0 + 10 = 10 10 - 9 = 1

So, the final result is 1.
