b. 35 – ( - 18 ) + ( - 21 )

c. – 17 + ( - 21 ) – ( - 19 ) – ( + 10 ) – [ - ( - 8 – 9 ) – 40 ]

d. – { ( - 21 ) –[ ( - 35 ) – (- 60 ) ] – ( + 42 ) – 30 }

e. – 8 + [ - ( 13 + ( - 5 ) ) – 4 + 16 ] – 15

Answer 1

Respuesta:

[ ( - 8 ) + ( - 15 ) + 16 ] – [ ( 19 ) + 24 – ( - 31 ) ]

[ - 8  - 15 + 16 ] – [ 19 + 24 + 31 ]

[ -7 ] – [ 74 ] = -7 -74 = -81

35 – ( - 18 ) + ( - 21 )

35 + 18 - 21 = 32

– 17 + ( - 21 ) – ( - 19 ) – ( + 10 ) – [ - ( - 8 – 9 ) – 40 ]

– 17 - 21 + 19 – 10 – [ - (-17) – 40 ]

– 17 - 21 + 19 – 10 – [ 17 – 40 ]

– 17 - 21 + 19 – 10 – [ -23 ]

– 17 - 21 + 19 – 10 + 23 = -6

 

– { ( - 21 ) –[ ( - 35 ) – (- 60 ) ] – ( + 42 ) – 30 }

– { - 21  –[ - 35 + 60 ] – 42 – 30 }

– { - 21  –[25] – 42 – 30 }

– { - 21  – 25 – 42 – 30 }

– { - 21  – 25 – 42 – 30 } = - {-118} = 118

– 8 + [ - ( 13 + ( - 5 ) ) – 4 + 16 ] – 15

– 8 + [ - ( 13 - 5 ) – 4 + 16 ] – 15

– 8 + [ - ( 8 ) – 4 + 16 ] – 15

– 8 + [ - 8 – 4 + 16 ] – 15

– 8 + [ 4 ] – 15

– 8 + 4 – 15 = -19
