Answer 1

Respuesta:

Operaciones combinadas:

$1-(-3+6+1)-[4-(6-3+1)-2] \\ 1 - (4) -[4 - (4) - 2] \\ 1 - (4) - (- 2) \\ = 7$

$\large\boxed{\bold{Rpta: 7}}$

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

6-(-3)-[3-(5)-1]

6-(-3)-[-3]

=12

$\large\boxed{\bold{Rpta: 12}}$

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

28-[21-(9)-7]

28-[5]

=23

$\large\boxed{\bold{Rpta: 23}}$

[-2+3.(2-5)÷3]-[(3-5+2)-2.(3-4)]

[-2+3.(-3)÷3]-[(0)-2.(-1)]

[-2+-3]-[(0)-(-2)]

[-5]-[-2]

=-3

$\large\boxed{\bold{Rpta: -3}}$

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

8-[6-(4)-6]+4

8-[-4]+4

=16

$\large\boxed{\bold{Rpta: 16}}$
