{[(30)(3)+40]-[(-12+3)(12-45+(-20+6)]÷12}=​​

Answer 1

Si te sirvio dale 5 estrellas o corona para seguir ayudando.

{[(30)(3) + 40] - [(-12 + 3)(12 - 45 + (-20 + 6)] ÷ 12}​​

{[90 + 40] - [(- 9)(12 - 45 + (-14)] ÷ 12}

{[130] - [(- 9)(12 - 45 - 14] ÷ 12}

{[130] - [(- 9)(- 47] ÷ 12}

{[130] - [423] ÷ 12}

{[130] - [423] ÷ 12}

{130 - 141/4}

379/4
