Answer 1

太多了，计算出全解要十几天，来一部分吧：

(333+333)*3+33/3=2009

(44-(4-44/4)/4)*44-4=2009

(6+6+6)/6*666+66/6=2009
6*6/(6+6)*666+66/6=2009
6/(6+6)*666*6+66/6=2009
6+6+((6+6+6)*666-6)/6=2009
((6+6+6)*(6+666)-6)/6-6=2009
6*(6+6*66-66)-6-6/6=2009
(66-6-6)*6*6-6/6+66=2009
66-6/6-6*6*(6+6-66)=2009
66-6/6-6*(6+6-66)*6=2009
66-6/6-6*6*(6-66+6)=2009
(66/6-6)*(66*6+6)-6/6=2009
66+6*(66-6-6)*6-6/6=2009
66-(6-66+6)*6*6-6/6=2009

(7+7)*(77+77/7)+777=2009
((7+77/7)*777+77)/7=2009
(77+(7+77/7)*777)/7=2009
(77+77)*(7+7/7)+777=2009
(7+(7+7)/7+7)*77+777=2009
(7+7-7)*(7*(7-77)+777)=2009
7-7+7*(7*(7-77)+777)=2009
7*(7*7+7+77+77+77)=2009
((7+7-7)*(7-77)+777)*7=2009
(7+7+(7+7+7)*(7+7-7/7))*7=2009
(7+7+7+7+7)*(7+7*7)+7*7=2009

(9*(999+999)+99)/9=2009
(99+9*(999+999))/9=2009
(99+999*9)/9+999=2009
(99+(999+999)*9)/9=2009
(9+9)/9+999+9+999=2009
99/9-(9-99/9)*999=2009
(99-(9*9-99)*999)/9=2009
((99-9*9)*999+99)/9=2009
(9+99+(9+9)*999-9)/9=2009
(999+9+9/9)*(9+9)/9-9=2009
(999+9+9/9)/9*(9+9)-9=2009
