[(1000-90):7:2+720:5-945:9:7]:2+3;
913-[13+(72:8+19)×33-576:8:3]

Answer 1

[(1000-90):7:2+720:5-945:9:7]:2+3=100

=(910:7:2+720:5-945:9:7):2+3

=(130:2+720:5-945:9:7):2+3

=(65+720:5-945:9:7):2+3

=(65+144-945:9:7):2+3

=(65+144-105:7):2+3

=(65+144-15):2+7

=(209-15):2+3

=194:2+3

=97+3

=100

913-[13+(72:8+19)*33-576:8:3]=

=913-[13+(9+19)*33-576:8:3]

=913-(13+28*33-576:8:3)

=913-(13+928-576:8:3)

=913-(13+928-72:3)

=913-(13+928-24)

=913-(941-24)

=913-917
