a) -10+12= b) -34+14= c) -20-17= d) 12÷(-4)=
e) -25÷5= f) -2×(+6)= g) (-104+68)÷(-24+30)=
h) (74-85)×(-4-9)= i) (-75+66)×(-4-8)=

Answer 1

a) =2 b) =-20 c) = -37 d) =-3 e) =-5 f)-12 g) =-6 h)=143 i) =108

Answer 2

Respuesta:

a) - 10 + 12=

+ (12 - 10)=

= 2

b) - 34 + 14=

- (34 - 14)=

= -20

c) - 20 - 17=

- (20 + 17)=

= -37

d) 12 ÷ (-4)=

- (12 ÷ 4)=

= -3

e) - 25 ÷ 5=

- (25 ÷ 5)=

= -5

f) - 2 × ( + 6)=

- ( 2 × 6)=

= -12

g) ( - 104 + 68) ÷ ( - 24 + 30)=

- 36 ÷ 6=

= -6

h) (74 - 85) × ( - 4 - 9)=

- 11 × ( -13)=

11 × 13=

= 143

i) ( - 75 + 66) × ( - 4 - 8)=

- 9 × (-12)=

9 × 12=

= 108

Espero te ayude
