Answer 1

Respuesta:

a) 6 – (5 - [4 – (3 - 2)])  = 4

b) 6 – (7 - [8 - (9 - 10)]) = 8

c) 10 + (11 - [12 + (13 – 14)])  = 10

d) 10 – (9 + [8 – (7 + 6)])  = - 6

e) [(3 – 8) - 5] + (-11 + [7 - (3 – 4)]) = - 13

Explicación paso a paso:

a) 6 – (5 - [4 – (3 - 2)])  = 6- (5-[4 – 1])  = 6- (5-3) = 6-2=4

b) 6 – (7 - [8 - (9 - 10)])  = 6 – (7 - [8 - (- 1)])  =6 - (7- [8 + 1]) =6-(7-9) =6-(-2) =6+2=8

c) 10 + (11 - [12 + (13 – 14)]) =10 + (11 - [12 + (– 1)]) =10 + (11- 11)  = 10+0= 10

d) 10 – (9 + [8 – (7 + 6)])  =10 – (9 + [8 – 1])  =10 – (9 + 7)  = 10-16 = -6

e) [(3 – 8) - 5] + (-11 + [7 - (3 – 4)])= [(– 5) - 5] + (-11 + [7 - (– 1)]) = -10+ (-11 + [7 +1)]) = -10+ (-11 + 8]) = -10+ (-3)= -13
