Answer 1

Hola!▪°▪

- 3 – { - 4 + [ - 2 + 5 + ( - 6 + 7) + 9 ] – 8} =

−3−(−4−2+5−6+7+9−8)

=−3−(−4+3−6+7+9−8)

=−3−(−4+3+1+9−8)

=−3−(−4+4+9−8)

=−3−(−4+13−8)

=−3−(9−8)

=−3−1

=−4

22 – ( - 4 + 3 – 1) + { - [ - 6 + ( 5 – 1) + 8 ] – ( - 8 + 3)} =

22−(−4+3−1)−(−6+5−1+8)−(−8+3)

=22−(−1−1)−(−6+5−1+8)−(−8+3)

=22−(−2)−(−6+5−1+8)−(−8+3)

=24−(−6+5−1+8)−(−8+3)

=24−(−6+4+8)−(−8+3)

=24−(−2+8)−(−8+3)

=24−6−(−8+3)

=24−6−(−5)

=24+−1

=23

( - 8 + 3 ) + { - [ - ( 6 + 5 – 4) – ( - 2 + 8)] + 9 – 3 } =−8+3−(−(6+5−4)−(−2+8))+9−3

=−5−(−(6+5−4)−(−2+8))+9−3

=−5−(−(11−4)−(−2+8))+9−3

=−5−(−7−(−2+8))+9−3

=−5−(−7−6)+9−3

=−5−(−13)+9−3

=−5+13+9−3

=−5+22−3

=−5+19

=14
