Answer 2

1. Starting with the first expression:

56 :(-7) + 3

Recall that when dividing by a negative number, the result is negative. Therefore, we have:

56/(-7) = -8

So the expression simplifies to:

-8 + 3 = -5

Therefore, the value of the expression is -5.

2. Moving on to the second expression:

-8 * (-5) + 75 :(-15)

Recall that when dividing by a negative number, the result is negative. Therefore, we have:

75/(-15) = -5

So the expression simplifies to:

(-8) * (-5) + (-5) = 40 - 5 = 35

Therefore, the value of the expression is 35.

3. Finally, let's simplify the third expression:

(12 – 28) : (-4) * 5

First, we need to evaluate the expression inside the parentheses:

12 – 28 = -16

Next, we divide by -4:

(-16) / (-4) = 4

Finally, we multiply by 5:

4 * 5 = 20

Therefore, the value of the expression is 20.
