Explicação passo-a-passo:
a)30+[6:(5-3)+1]= 59 b)20-[6-4 x(10-3+1)]=-16 c)50+[3:(1+2)+ 4 x 3]=
30+[36:(5-3)+1]= 20-[+2 x(10-9+1)]= 50+[27:(1+2)+4 x 3]=
30+[36:+2+1]= 20-[+2 x(+1+1)]= 50+[27:+3+4 x 3]=
30+[+28+1]= 20-[+2 x+2]= 50+[27:+7 x 3]=
30++29= 20-+4= 50+[27:+21]=
+59 -16 50++1=
+51
d)100-[5:(10-5)+2 x 1]= e)[4+(5-3)³]:(9-7)³= f)7+2 x[(3+1)²-4 x 1]=
100-[25:(10-5)+16 x 1]= [16+(5-3)³]:(9-7)³= 49+2 x[+4²-4 x 1]=
100-[25:+5+16]= [16++2³]:+2³= +51 x[+8 -4 x 1]=
100-[+5+16]= [16++8]:+8= +51 x[+8 -3]=
100-+21= +24:+8= +51 x +5=
+121 +3 +255
