Insert some four arithmetic symbols between the nine numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 arranged in ascending order (if no symbols are inserted between adjacent numbers, it is considered that they form a multiple digits), so that the final operation result is equal to 2004. Give two solutions that satisfy the above requirements.
在从小到大排列的九个数字1，2，3，4，5，6，7，8，9之间插入一些四则运算符号(如果相邻数字之间未插入符号，就认为它们组成了多位数)，使最后的运算结果等于2004．请给出两个满足上述要求的解答．
