Owners of one restaurant have left diners stumped with a mind-boggling Wi-Fi brain teaser.
近日，一家餐厅的老板出的一道超级复杂的Wi-Fi智力题难倒了一众来此用餐的食客。
It appears the owners of YaYa's Thai restaurant in Texas, US, have a strange sense of humor after putting up a poster with a mathematical equation for the password.
这起事件发生在美国德克萨斯州的一家YaYa's泰国餐厅。经营者似乎有种奇怪的幽默感，他们贴出了一张写有数学方程式的纸，解开方程式才能获得密码。
A photo of the sign was posted to social website Reddit, where users - even those well-versed in math - were equally perplexed.
有人将这张纸的照片上传到了社交网站Reddit上，而Reddit的用户，即使是其中精通数学的网友都被难住了。
Some users suggested the problem was a trick question, while others said the math equation appears to have several solutions.
一些用户认为此题是道捉弄人的问题，另一些用户则称这道数学方程式似乎有多种答案。
One said the equation was a 'summation of a binomial probability density function' - and we have no idea what that means either.
还有个用户则称，这道方程式是“二项式概率密度函数求和”--然而我们仍找不到答案。
The user who uploaded the photo promised to attempt some of the suggested solutions and report back with his findings.
上传照片的Reddit用户承诺，会对部分网友给出的答案进行尝试，并对其结果进行报告反馈。
It is unclear why Yaya's owners decided to make it so difficult to log on at the restaurant. However, some have suggested it could be that they became tired of people stealing the signal.
目前还不清楚为何Yaya's的老板想出一道如此难的题目以阻止顾客上网。不过，也有人认为他们厌倦了大家蹭网的行为。
