(-2)(+42):(-7)-(-64):(+16)(-1)
17-(-1+8-3-9)
(-3)(-4)-(36):(+6)
[(-2)(+4)]²:(-2³)+[(-32):(+16)]³
(-2).(-3)+(-1+5)
(-12+10).(-20+30)
(+20-5)x(+12-4)-(-1+3)

Answer 1

(-2)(+42):(-7)-(-64):(+16)(-1)=
-2 -6 - (-4)(-1) =
-2 -6 - (+4)=
-2 -6 - 4 = - 12
_______________________________
17-(-1+8-3-9)=
17-(-5) = 17+ 5 = 22
_________________________
(-3)(-4)-(36):(+6)=
+ 12 - 6 = 6
_____________________________
[(-2)(+4)]²:(-2³)+[(-32):(+16)]³=
[-8]² : (-8) + [-2]³= 64 :(-8) +[-8]= -8 - 8 = -16
_________________________________
(-2).(-3)+(-1+5)=
+6 + 4 = 10
___________________________________
(-12+10).(-20+30)=
-2 . 10 = - 20
________________________________
(+20-5)x(+12-4)-(-1+3)=
15 x 8 - 2 = 120 - 2 = 118
