Answer 1

Explicación paso a paso:

Tener en cuenta la regla de los signos:

+*+=+

-*-=+

+*-=-

-*+=-

9+7+3=19

(-15):(-3)=+5

28:7=4

100:5=20

49-(+12)=

49-12=37

(-8)+(+12)+(-6)-(+5)=

-8+12-6-5=-7

(9)*(-4)=-36

(48):(12)=

48:12=4

5*(-4)*(-6)=

-20*(-6)=+120

-72:9=-8

[(-5)*(+4)]*(-2)=

[-20]*(-2)=+40

[(-2)*(-8)]*(+5)=

[16]*5=+80

(-5)*[(-7)*(-12)]=

(-5)*[+84]=-420

(+3)*[(-6)*(+4)]=

(+3)*[-24]=-72

Espero te ayude!!
