corregirán los cálculos que no cumplan con todos estos pasos)
1) 3 - { 2 - 3 - [ - 2 + (1 + 3)] - 3} =

2) 2 + 3 - {2 - [2 - 3 + 1] - 2 - (3 - 1)} - 2 =

3) 2 - 4 - (- 2 - 3) - {2 - [- 2 - ( - 2 + 3)] - 1} + 2 =

4) 1 + { 5 + 4 - 3 - 9 – [ 5 + 8 - 7 - ( 7 + 8 - 9 – 23 ) – 5 ] + 3 }

Answer 1

Respuestas y procedimientos:

No. 1:

$3 - (2 - 3 - [ - 2 + (1+3)] - 3)=\\3 - (2 - 3 - [ - 2 + (4)] - 3)=\\3 - (2 - 3 - [ 2] - 3)=\\3 - (2 - 3 - 2- 3=)\\3 - (-6)=\\3+6=\\9$

No. 2:

$2 + 3 - (2 - [2 - 3 + 1] - 2 - (3 - 1)) - 2 =\\2 + 3 - (2 - [0] - 2 - (2)) - 2 =\\2 + 3 - (2 - 0 - 2 - 2) - 2 =\\2 + 3 - ( - 2) - 2 =\\2 + 3 + 2 - 2 =\\2 + 3 = \\5$

No. 3:

$2 - 4 - (- 2 - 3) - (2 - [- 2 - ( - 2 + 3)] - 1) + 2 =\\2 - 4 - (-5) - (2 - [- 2 - ( 1)] - 1) + 2 =\\2 - 4 - (-5) - (2 - [- 3] - 1) + 2 =\\2 - 4 - (-5) - (2 +3 - 1) + 2 =\\2 - 4 - (-5) - (4) + 2 =\\2 - 4 + 5 - 4 + 2 =\\-2 + 5 - 2 =\\1$

No. 4:

$1 + ( 5 + 4 - 3 - 9 - [ 5 + 8 - 7 - ( 7 + 8 - 9 - 23 ) - 5 ] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 5 + 8 - 7 - ( 6 - 23 ) - 5 ] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 5 + 8 - 7 - ( -17 ) - 5 ] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 5 + 8 - 7 + 17 - 5 ] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 5 + 8 +10 - 5 ] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 8 +10] + 3 )=\\1 + ( 5 + 4 - 3 - 9 - [ 18] + 3 )=\\1 + ( 5 + 1 - 17 + 3 )=\\1 + ( -8 )=\\1-8=\\-7$
