Answer 1

Respuesta:

a) 4 + 6 - 2 + (5 - 3 + 6) - 4+ 9 - (12 + 9) = 0

b) (9-3 + 5 - 4) + (15 - 12 + 10) - (16 - 15 +14) = 5

c) 8-6+ (9-5) - (10-8) + 12 - (3 +2 -1) + 4 = 16

d) 9 + 7-4 - (3 + 5) + (6 - 3+ 8) - (9 + 10 - 15) =11

e) 13 + 15 -9 + (6-3) -(8 + 7) - 4 + 2 + (12- 9) = 8

D 15 + 25 - (6 +19) + 4- (8 + 10) + (6 -5 + 1) = 3

g) 21 + (17 - 13) - (12 + 4) - 8+ (9-3 +15) - 1 = 21

h) (4 + 12) - (9 + 5) + (8 + 17) - (9 - 6) + (9-5) - 8 =20

i) 21 - 13 + (8-5) - (16 - 9) + (15-3 + 8) - 10 = 14

j) 27-(19 + 7) + (26 - 19) -5+ (9-8) + 11 = 15

k) 57 - (20 + 4) - (16 - 12) + (14 - 11 + 2) = 34

1) 42-(17 + 12 - 9 + 10) + (15 – 11 + 7) - (16+5) =62
