4. 25

5. - 84

6. -240

7. 100

8. -13

9. 45

10. - 6

Step-by-step explanation:

1. (-8) + ( -5) equal to -8 - 5 = - 13 it will be add then copy the common sign

2. 10 + (-4) equal to 10 - 4 = 6 just multiply the sign if (possitive x negative) the answer is always negative.

3. (-9) - 17 = - 26, just like the number 1 we need to add then copy the sign.

4. 12 - (-13) = 25 this time, we need to multiply negative x negative and the answer would be positive.

5. (7) (-12) = -84, multiply then multiply also the sign

and so on.
