3)

-3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

I) 7-(-4) =7+4=11

ii) 5

4) I) 117 ii) 18

5) sucessor of -27 = -26

predecessor of -39= -40

-26-(-40) =-26+40=14

6) please post the complete question

7) 18 m above sea level = +18

13 below sea level = -13

18-(-13) =18+13=31

8) -5376+3744= -1,632

-2150+112= -2,038

-1632-(-2038) =-1632+2038=406

9) - 12 + (-7) + 36 + (- 32) + (- 49)

= -12-7+36-32-49 = -100+36= -64

10) -23-145= -168

I hope my answer helps you☺☺
