Answer 1

Respuesta:

a. -3

b. 1

c. 170

d. -1

Explicación paso a paso:

a. 2-6-(-1)

-4-(-1)

-4+1= -3

b. 7-(4)-(2)

3-(2) = 3-2= 1

c. - 6 ⋅ { [ 4 + ( - 18 ) ] - 14 } - ( - 2 ) =

= - 6 ⋅ { [ - 14 ] - 14 } - ( - 2 ) =

= - 6 ⋅ { - 28 } - ( - 2 ) =

= 168 - ( - 2 ) =

= 170

d. 12 + [ 5 - 2 ⋅ ( 12 ) ] + 6 =

= 12 + [ 5 - 24 ] + 6 =

= 12 + [ - 19 ] + 6 =

= - 7 + 6 =

= - 1
