​

Answer 1

Explicación paso a paso:

a. 1-(-3+6+1)-(4-(6-3+1)-2) =

1-(4)-(4-(4)-2)

1-4-(4-4-2)

-3-(-2)

-3+2 =-1

Answer 2

Explicación paso a paso:

1 - (-3 + 6 + 1) - (4 - (6 - 3 + 1) - 2)

= 1 - 4 - (4 - 4 - 2)

= (-3) - (-2)

= (-3) + 2

= - 1

6 - (-9 + 7 - 1) - (3 - (-5 + 4 + 6) - 1)

= 6 - (-3) - (3 - 5 - 1)

= 6 + 3 - (-3)

= 9 + 3

= 12

28 - (21 - (12 - 3) - 7)

= 28 - (21 - 9 - 7)

= 28 - 5

= 23

(-2 + 3 - (2 - 5) : 3) - (3 - 5 + 2) - 2 * (3 - 4)

= (-2 + 3 - ((-3) : 3) - 0 - [2 * (-1)]

= (1 - (-1) - (-2)

= 1 + 1 + 2

= 4

8 - (6 - (-3 + 7) - 6) + 4

= 8 - (6 - 4- 6) + 4

= 8 - (-4) + 4

= 8 + 4 + 4

= 16
