Answer 1

 (-42):(-7)-9 =
6-9=
-3

18-4 . 5 =
18-20=
-2

(4-6) . (-5) =
(-2)(-5)=
10

(-16) : (9-5) =
(-16):(-4)=
4

24: (-6)+2 =
-4+2=
-2

13-4 . 24=
13-96=
-83


(-35): 7+2 =
-5+2=
-3

18:(-9)=
-2

15-(-3 . 4 +7) =
15-(12+7)=
15-19=
-4

8: 2-5-3=
4-8=
-4

(2 . 3-9)+4 =
(6-9)+4=
-3+4=
1

(16-4) : 4-8 =
12:4-8=
3-8=
-5

 15:5-8 . 2 + 6 =
3-16+6=
-7

 (6 . 2-8 . 2) . 5: (-2) =
(12-16)5:(-2)=
5(-4):-2=
10

3 . (-5) + 4 . 3 - 18:3 =
-15+12-6=
