Answer 1

Respuesta:

A)-1

B)13000

C)2585

Explicación paso a paso:

A) -[(-20).(+5): (-4)]-[36+(22). (-2)]-(-8. (+2)

-[(-20).(+5): (-4)]-[36+(-44)]-(-8. (+2)

-[(-20).(+5): (-4)]-[36-44]-(-8. (+2)

-[(-20).(+5): (-4)]-[-8]-(-8). (+2)

-[(-20).(+5): (-4)]-[-8]+8. (+2)

-[(-20).(+5): (-4)]+8+8. (+2)

-[(-20).(+5): (-4)]+8+16

-[-100: (-4)]+8+16

100: (-4)]+8+16

-25+8+16

-17+16

-1

B) {12-[45 : (-9 )+(-6).(-1)- (5) +3]}. (1000)

{12-[-5+(-6).(-1)- (5) +3]}. (1000)

{12-[-5+6-(5)+3]}. (1000)

{12-[1-(5)+3]}. (1000)

{12-[-4+3]}. (1000)

{12-[-1]}. (1000)

{12+1}. (1000)

13. (1000)

13000

C) { [7 .5 - (-30)]. [28: (-2-5)}. (-10)-(3.5)

{ [7 .5 - (-30)]. [28: (-7)}. (-10)-(3.5)

{ [7 .5 - (-30)]. (-4)}. (-10)-(3.5)

{ [7 .5 +30]. (-4)}. (-10)-(3.5)

{ [35 +30]. (-4)}. (-10)-(3.5)

(-260). (-10)-(3.5)

2600-(3.5)

2600-15
