[(1×2×3×4+5)+(2×3×4×5-6)+1]:3-[(3×4×5×6+7)+(4×5×6×7+8)-(6×7×8×9-1760-49):45]:36=va rog ajutati-ma!

Answer 1

=[(2*12+5)+(6*20-6)+1]:3[(12*30+7)+(20*42+8)-(42*72-1760-49):45]:36
=[(24+5)+(120-6)+1]:3[(360+7)+(840+8)-(3024-1711):45]:36
=(29+114+1):3[367+848-3024):1760-49):45]:36
=(29+115):3[(1215-1264-49):45]:36
=144:3-[(1215-1215):45]:36
=48-(0:45):36
=48-0:36
=48-0
=48
