Resposta:
-9877
Explicação passo-a-passo:
123+ ( 100 + 10 x 90 ) x ( 3 x 2 - 2 x 8 )
multiplique 10 x 90
123+ ( 100 + 900 ) x ( 3x2 - 2 x 8)
multiplique 3x2
123+ ( 100 + 900 ) x ( 6 - 2 x 8)
multiplique 2x8
123+ ( 100 + 900 ) x (6- 16)
some 100 + 900
123 + 1000 ( 6 - 16 )
123 + 1000 x ( -10)
multiplique 1000 x ( -10)
123-10000
calcule a diferença
