野草的乐趣就是疯长。而且,杂草丛生的地方才是最自然、最接近本质、最能触摸到心跳的地方。

儿子今天的数学作业

(2008-10-06 16:48:25) 下一个
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。
