Answer 1

Explicación paso a paso:

•(-3+5-9)+(5-6+3)-(3+9-6+2)

(2-9)+(5-6+3)-(3+9-6+2)

(-7)+(5-6+3)-(3+9-6+2)

-7+(5-6+3)-(3+9-6+2)

-7+(-1+3)-(3+9-6+2)

-7+(2)-(3+9-6+2)

-7+2-(3+9-6+2)

-7+2-(12-6+2)

-7+2-(6+2)

-7+2-(8)

-7+2-8

-5-8= -13

•(7+6+9+5)-(-2-6-9-7)

(13+9+5)-(-2-6-9-7)

(22+5)-(-2-6-9-7)

(27)-(-2-6-9-7)

27-(-2-6-9-7)

27-(-8-9-7)

27-(-17-7)

27-(-24)

27+24= 51
