Answer 1

-5²+(-3) × (-1+7)-[+3-5×(-1+2)]=
25+(-3) x (6)-(-2 x-1)=
25-3 x 6 x 2=
22x6x2=
132x2=264
Resultado final: 264

Answer 2

$- {5}^{2} + ( - 3) \times ( - 1 + 7) - (3 - 5 \times ( - 1 + 2)) \\ - {5}^{2} + ( - 3) \times (6) - (3 - 5 \times 1) \\ - {5}^{2} + ( - 18) - ( - 2) \\ - {5}^{2} - 18 + 2 \\ 25 - 18 + 2 \\ 7 + 2 \\ 9$
