Answer 1

Respuesta:

(10 – 7) – (–2 – 6) =   3 + 8 = 11

10 – [ 6 + (2 + 7) ] =  10 [ 6 + 9 ] = 10 - 15 = - 5

– (6 – 2) – (7 – 9 )=  – 4  – (-2 ) = - 4 + 2 = -2

(5 – 12) – (8 – 6) = - 7 - (2) =  -7 - 2 = -9

(–6 ) + [ 5 + (2 – 12) ] =  - 6 + [ 5 + (10) ] = - 6 + 15 = 9

4 + (+3 – 8) = 4 + (+3 – 8) = 4 + - 5 = -1

– (8 + 4) + (5 – 9) =  - 4 - 4 = -8

8 + [ 4 – (3 + 5) ] =  8 + [ 4 – (8) ] = 8 +  [- 4 ] = 8 - 4 = 4

15 – [ 2 – (6 – 10) ] =  15 – [ 2 – (- 4) ] = 15 – [ 2 + 4 ] = 15 - 6 = 9

12 – [ 7 – (2 – 10) ] =  12 – [ 7 – (- 8) ] =  12 – [ 7 + 8 ] = 12 – 15 = - 3

10 – (–7 – 5) =  10 – (- 12) = 10 + 12 = 22

11 + (–5 – 9) =  11 + (- 14) = 11 - 14 = - 3

15 – [ 10 – (8 + 4) ] =  15 – [ 10 – (12) ] = 15 – [ - 2 ] =  15 + 2 = 17

13 + (–8 + 2) = 13 + (–8 + 2) = 13 - 6 = 7

6 + [ 5 - (7 + 2) ] = 6 + [ 5 - (9) ] = 6 + [- 4 ]  = 2
