Question

Calcule:
180 - {120 + [60 + (40 - 80) + 90] - 10}

Answer 1

$\sf180-\{120+[60+(40-80)+90]-10\}$

$\sf 180-\{120+[60+(-40)+90]-10\}$

$\sf 180-\{120+[20+90]-10\}$

$\sf180-\{120+110-10\}$

$\sf180-\{220\}$

$\sf180-220$

$\red{\sf -40}$

Answer 2

Resposta:

É -40

Explicação passo a passo:

180 - {120 + [60 + (40 - 80) + 90] - 10}->(40-80)= -40->[60+(-40)+90]= 110

-> {120+110-10}= 220-> 180 - {220}= -40.
