Me ajudeem pf !!!!

Answer 1

A) 5 + 2 + 3 = 10
B) 14 + 6 + (-2) =
14 + 6 - 2 =
20 - 2 = 18
C) -11 - 3 + 5 - 2=
-14 + 3 = - 11
D) 16 - [-2 + 10]=
16 - [+8] =
16 - 8 = 8
E) -35 + {7 - [-12 - 18 + 1 - 16]} =
- 35 + {7 - [- 30 - 15]} =
- 35 + {7 - [- 45]} =
- 35 + {7 + 45} =
- 35 + 52 = + 17
F) + 11 + 72 = 83
