Answer 1

Respuesta:

-

a. 12+( {-10-(-8+2) }÷2}

12+((-10-(-6)) ÷ 2)

12+((-10+6) ÷ 2)

12+(-4÷2)

12+(-2)

12 - 2

= 10

b. 4×3+{5-2(8+4)}+6

12+(5 - 2 × 12) +6

12+(5-24)+6

12+(-19)+6

12-19+6

= -1

c. -6×{ (-32÷8+ (9-27) )-14}-(-2)

-6 ((-4+(-18)) -14)+2

-6 ((-4-18)-14)+2

-6 ((-22)-14)+2

-6 (-22-14)+2

-6×(-36)+2

216+2

= 218
