ahi esta coronita please
:D
Explicación paso a paso:
a) - 5 – (-8) + {-9 – [-6 + (5 - 9)] – [9 – 7 - 6]}
−5−(−8)−9−(−6+5−9)−(9−7−6)
3−9−(−6+5−9)−(9−7−6)
3−9−(−6+−4)−(9−7−6)
3−9−(−10)−(9−7−6)
3+1−(9−7−6)
3+1−(2−6)
3+1−(−4)
3+5

b) – {-7 + [-6 + 15 – (-9 + 13 + 17) – (6 - 5)]}
-{-7+[-6+15-(-9+13+17)-(6-5)]}
-{-7+[-6+15-21-1)]
-[-7+(-13)]
-(-7-13)
-(-20)

c) - 9 -[15 – (7 - 8) - 6] – [9 – (6 - 3)]
-9-(15-(-1)-6)-(9-3)
-9-(15+1-6)-6
-9-10-6
-25
d) – {14 – [9 – (6 - 17) - 3] – [-5 – (8 – 3 - 7)]}
-{14-[9-(-11)-3]-[-5-(-2)]}
-{14-[9+11-3]-[-5+2]}
-{14-[17]-[-3]}
-{14-17+3}
