儿子今天的家庭作业，第八题：Write a place-value number riddle. 于是他就草就了如下这么个数谜： My thousands digit is more than 3 and also a multiple of 4. My hundreds digit is 2 more than my thousands digit. My tens digit is the hundreds digit times two, then minus 3. My ones digit is a multiple of 3 and is divisible by 2. The number in my tenths place is 1111/2222 turned into a part of a number. The number in my hundredths is not 1 or 7, and isn’t any number divisible by 3. It is not 2 or 8 either. The thousandths digit is 5 more than my hundredths digit. What number am I? 儿子对我说：一个月以后再给答案。 儿子已授予我发表此文的版权。
