Explicación paso a paso:

a. 4 + { 5 – 4 – ( 50 ÷ 5 ) + 7 } – 1

4 + { 5 – 4 – ( 10 ) + 7 } – 1

4 + { 1 – 10 + 7 } – 1

4 + { - 9 + 7 } – 1

4 + { - 2} – 1

4 + - 2 – 1

-10 -5

-15

c. 2 – { - 2 + ( 4 – 7 ) * ( 7 – 9 ) – 1 }

2 – { - 2 + ( - 3) * ( - 2) – 1 }

2 – { - 2 + - 3*– 2 – 1 }

2 – { - 2 + 6 – 1 }

-9 +1 - 2

-8 - 2

-10

e. { - 2 ÷ 2 + [ - 2 – 4 + ( 3 – 2 ) ] – 1 } – 9

{ - 2 ÷ 2 + [ - 2 – 4 + ( 1 ) ] – 1 } – 9

{ - 2 ÷ 2 + [ - 2 – 4 + 1 ] – 1 } – 9

{ - 2 ÷ 2 + [ - 5 ] – 1 } – 9

{ - 2 ÷ 2 - 5 – 1 } – 9

{ - 1 - 5 – 1 } – 9

{ - 7 } – 9
