Answer 1

1+918:{[12+3x(576:12-4x12)]:4+6}=1+918:{[12+3x(48-48)]:4+6}=1+918:[(12+3x0):4+6]=1+918:(12:4+6)=1+918:(3+6)=1+918:9=1+102=103

{507+15x[15x(15x(318:53+408:34):45-6]:21}:13={507+15x[15x(15x(6+12):45-6]:21}:13={507+15x[15x(15x18:45-6]:21}:13={507+15x[15x(6-6]:21}:13={507+15x[15x0:21}:13={507+0}:13=39
