{1+2[3+4•(5•6+7)]}:3-100

Answer 1

{1+2[3+4·(5·6+7)]}:3-100=
=[1+2(3+4·37)]:3-100=
=[1+2(3+148)]:3-100=
=(1+2·151):3-100=
=303:3-100=
=101-100=
=1

Answer 2

{1+2*[3+4*(5*6+7)]}:3-100=
={1+2*[3+4*(30+7)]}:3-100=
=[1+2*(3+4*37)]:3-100=
=[1+2*(3+148)]:3-100=
=(1+2*151):3-100=
=(1+302):3-100=
=303:3-100=
=101-100=1
