B) - { 3 – 4 . ( 2 + 5 – 9 ) – ( 4 + 8 – 10 – 6 + 7 ) – 5 } + 3 =








C) (5 + 4 – 8 ) ( 9 + 5 – 8) + 200 =








D) -2 . {-3 ( 5+ 4 – 3 – 6 ) – ( 2 + 4 + 8 – 9)} + 7 =

Answer 1

Respuesta:

A = -6+ { -2 + 3 [2 (-3)-(-3)+(-2)]-4}+5

A = -6 + { -2 + 3 [ -6 + 3 - 2 ] -4 } + 5

A = -6 + { -6 + 3 - 2 - 4 } + 5

A = -18 + 8

A = 10

B = - { 3 – 4 . ( 2 + 5 – 9 ) – ( 4 + 8 – 10 – 6 + 7 ) – 5 } + 3 =

B = - { 3 - 4 ( - 2 ) - ( 3 ) - 5 } + 3

B = - { - 2 - 3 - 5 } + 3

B = 10 + 3

B = 13

C = (5 + 4 – 8 ) ( 9 + 5 – 8) + 200

C = 1 * 6 + 200

C = 206

D= -2 . {-3 ( 5+ 4 – 3 – 6 ) – ( 2 + 4 + 8 – 9)} + 7

D = -2 * { -3 ( 0 ) - ( 5 ) } + 7

D = -2 * {0 - 5 ) } + 7

D = -2 * { -5 } + 7

D = 10 + 7

D = 17
