h)
95-[25:5+(4*3-6)]+786:6=
95-[25:5+(12-6)]+786:6=
95-(25:5+6)+786:6=
95-(5+6)+786:6=
95-11+131=
84+131=
215
i)
[84+(105*4)-(39*2)-298]:(6912:108)=
[84+420-78-298]:64=
(504-78-298):64=
(426-298):64=
128:64=
2
j)
314-2*(21-4)=
314-2*17=
314-34=
280
k)
9*(101+111)-[85-7*(4+7)]=
9*212-[85-7*11]=
9*212-(85-77)=
9*212-8=
424-8=
416
l)
324:[108:(21+6*5:30+5)]+19=
324:[108:(21+30:30+5)]+19=
324:[108:(21+1+5)]+19=
324:(108:27)+19=
324:4+19=

100
m)
101-300:[24-21:(42-6-15)+196:28]=
101-300:[24-21:(36-15)+196:28]=
101-300:[24-21:21+196:28]=
101-300:(24-1+7)=
101-300:30=
