Answer:

11. -3 - (-8) = 5

12. -10 + (-25) = -35

13. -11 - (-10) = -1

14. 12 + (-5) = 7

15. -9 (9 + (-9) = 0)

Step-by-step explanation:

I don't really know how to explain it. For 11 I just found found the difference kind of. It's easier if you draw out a number line. 12 is self - explanatory, you just add the two negative numbers and it will be a negative. I look at 14 as just another minus equation.

Answer:

11. 5

12. -35

13. -1

14. 7

15. -9

Step-by-step explanation:

11. -3-(-8)

= -3 + 8 (double negative is positive)

= 8-3

= 5

12. -10 + (-25)

= -10 -25 (positive negative is negative)

= -35

13. -11 - (-10)

= -11 + 10

= -1

14. 12 + (-5)

= 12 - 5

= 7

15. 9 + x = 0

x = 0 - 9

x = -9
