Resposta:

Explicação passo-a-passo:

A)verifique se está correta...

B){42+[(45-19)-(18-3)+1]}=

{42+[26-15+1]}=

{42+12}=

= 54

C)15•12-30:3+7=

180-10+7=

170-7=

= 163

D) (6•3•10):(15-3)•16=

180:12•16=

15•16=

= 240

E)86+(31-16+60)-(200-70-5)=

86+(15+60)-(130-5)=

86+75-125=

161-125=

= 36
