-(40-35+12-15+5-(35-20)-(18-15)+24+36(12-4)-7-3)-9

=-(5+12-15+5-(35-20)-(18-15)+24+36(12-4)-7-3)-9

=-(17-15+5-(35-20)-(18-15)+24+36(12-4)-7-3)-9

=-(2+5-(35-20)-(18-15)+24+36(12-4)-7-3)-9

=-(7-(35-20)-(18-15)+24+36(12-4)-7-3)-9

=-(7-15-(18-15)+24+36(12-4)-7-3)-9

=-(-8-(18-15)+24+36(12-4)-7-3)-9

=-(-8-3+24+36(12-4)-7-3)-9

=-(-11+24+36(12-4)-7-3)-9

=-(13+36(12-4)-7-3)-9

=-(13+(36)(8)-7-3)-9

=-(13+288-7-3)-9

=-(301-7-3)-9

=-(294-3)-9

=-291-9

=-300
