nesesito ayuda porfavor rapido

Answer 1

A) 2 - {6 - [4+ (2-1) - (2-1) -2]} -4
2 - {6 - [4+ (1) - (1) -2]} -4
2- {6 - [4 +1 -1 -2]} -4
2- {6 -[2]} -4
2- {6 -2} -4
2- {4} -4
2 -4 -4= -6

B) 4 + [-1 + (9-2)] -9 +(1-2)
4 + [-1 + 7] -9 -1
4 + 6 -9 -1 = 0

C) 19 -51 +17 - [12 -(25 +47 -34)]
19 -51 +17 - [12 -25 -47 +34]
19 -51 +17 - [ -26 ]
19 -51 +17 +26 = 11

D) 1 -{2 -[3 -(4 -5) -6] -7}
1 - {2 -[3 -(-1) -6] -7}
1 - {2 -[3 +1 -6] -7}
1 - {2 - [-2] -7}
1 - {2 +2 -7}
1 - {-3}
1 +3 = 4

E) 2 - {6 -[-4+(2-1) - (2-1) -2]} -4
2 - {6 -[-4 +1 - (1) -2]} -4
2- {6 -[-4 +1 -1 -2]} -4
2 - {6 - [-6]} -4
2 - {6 +6} -4
2 - {12} -4
2 -12 -4 = -14
