Answer 2

$\sf{segue \: abaixo \: a \: resposta}$

$\sf{102-{+25-[-12(+5+8)-(+4.(-7)]-8}}$

$\sf{102 - (25 - ( - 12x13 - (4x( - 7)) - 8)}$

$\sf{102 - (25 - ( - 12x13 - ( - 28)) - 8}$

$\sf{102 - (25 - ( - 156 - ( - 28)) - 8)}$

$\sf{102 - (25 - (156 + 28) - 8)}$

$\sf{102 - (25 - ( - 128) - 8)}$

$\sf{102 - (25 + 128 - 8)}$

$\sf{25 + 128 - 8 = 145}$

$\sf{102 - 145}$

$\boxed{\boxed{\sf{ - 43}}}$
