Question

10. Halla el valor de estas expresiones:
a) 6 - (5 - 3) - [7 - (-1 - 4)]
b) -(5 + 6) - [-4 - (7 + 3)]
c) 10 -[-6 + (-8) -4] - (-3 -2)
d) -7 +3 - [-(10 - 5) - (8 -10)]
e) - [8 - (7 + 3) (1 - 9)] - (4 - 8 + 2)
f) 9 + [15 +(7 -10)] - [8 - (7 + 3) + (-2)]

Answer 1

Respuesta:

a) 6 - (5 - 3) - [7 - (-1 - 4)]

6-(2)-(7-(-5))

6-2-7+5

4-2 = 2

b) -(5 + 6) - [-4 - (7 + 3)]

-(11)-(-4-(10))

-11-(-4-10)

-11-(-14)

-11+14 = +3

c) 10 -[-6 + (-8) -4] - (-3 -2)

10-(-6-8-4)-(-5)

10-(-18)+5

10+18+5 =33

d) -7 +3 - [-(10 - 5) - (8 -10)]

-4-(-(5)-(-2))

-4-(-5+2)

-4-(-3)

-4+3 = -1

e) - [8 - (7 + 3) (1 - 9)] - (4 - 8 + 2)

-(8-(7-63+3-27))-(-2)

-(8-(-80))+2

-8+80+2= +74

f) 9 + [15 +(7 -10)] - [8 - (7 + 3) + (-2))

9+(15+(-3))-(8-10-2)

9+(15-3)-(-4)

9+(12)+4

9+12+4 = +25
