In the US, customers of a Thai restaurant are cracking their brains in order to solve a complex math equation which is the password to the eatery’s WiFi.
YaYa’s Thai restaurant in San Antonio, Texas, posted its “WiFi password” just above the sign about minimum credit card purchase amounts, but the Internet access has proven difficult for customers to come by because the “password” is listed as a math equation.
A photo of the sign was posted to Reddit, where users were equally perplexed.
The user who uploaded the photo promised to attempt some of the suggested solutions and report back with his findings.
Some users suggested the problem was a trick question, while others said the math equation appears to have several solutions.
