Answer 2

Respuesta:

(-3).[(+7)+(-2)]

(-3).[7-2]

(-3)*5= -15

(6-2-10):(5-11)

(-6):(-6)= 1

(+5).[(-3)+(-7)]

(5).[-3-7]

(5)*[-10]= -50

27+3.5-16

27+15-16=26

27+3-45:5+16

30-9+16=37

(2.4+12)(6-4)

(8+12)*(2)

20*2=40

3.9+(6+5-3)-12:4

27+(11-3)-3

27+8-3=32

2+5(2.3)

2+5*6

2+30=32

440-[30+6(19-12)]

440-[30+6(7)]

440-[30+42]

440-[72]

440-72=368

9:(-3)+8.(-5)+36

-3+(-40)+36

-3-40+36= -7

(-12).4-(-32):8-(-5)

-48-(-4)+5

-48+4+5= -39

65:(-5).2+28:(-7)

-13*2+(-4)

-26-4= -30

(-4)-32:(-8)+2.(-6)

-4-(-4)+(-12)

-4+4-12= -12

15-(.40):10+15:(-5).2

15-4+(-3)*2

11+(-6)

11-6=5

63:(-3)-9-(-7)+1

-21-9+7+1= -22

(-7).(12:(-2)+3)-10

(-7)*(-6+3)-10

(-7)*(-3)-10

21-10=11

(12-3.5)+10:(-2)

(12-15)+(-5)

-3-5= -8

18:(-9)+(-3)-(-2)+5

-2-3+2+5=2

-2+(-3).(-4)

-2+(12)

-2+12=10
