Answer 1

31-29:{1+112:[0+20:20×4+0]}= 31-29:{1+112:[0+1×4+0]}= 31-29{1+112:[0+4+0]}= 31-29[1+112:4]= 31-29:(1+28)= 31-29:29= 31-1= 30

Answer 2

31-29:{1+112:[0:5+20:(2•5•2)•4+7•0]}= 31-29:{1+112:[0:5+20:(10•2)•4+7•0]}= 31-29:[1+112:(0:5+20:20•4+7•0)]= 31-29:[1+112:(0+1•4+0)]= 31-29:(1+112:4)= 31-29:(1+28)= 31-29:29= 31-1= 30
