猫猫头,nice to see you again. I don't know what it is, this is reason I need to ask you guys. I got it from a Jfriend's JJ of this month, the answer is D, but I don't know what it means. Please help me work it out, thanks.

可是猫猫头也看不懂哎，
题目好象不完整

jackco

what is the symbol of Min and Max here?

It seems a couple of Gmaters have met the math in their test.So it is important to understand what it means. 猫猫头, after you understand it, please tell me as soon as possible.

jackco：这个题目是不完整的，请查阅我在前面总结的10月机警，里面有完整的题目和解答。

9月的JJ里面有一道类似的题，它是把字母换成了W和w，好象是在9月JJ里数学总结中的三部分，可能是9月16号以后的， 我记不太清楚了。大概是40-60之间的一题里出现过。

yiyuan05, could you tell me the password of 9-month JJ? I couldn't open it.
