A San Antonio Thai restaurant, Yaya, will let you use its Wi-Fi for free-- but only if you can solve this insanely complex math equation.
Reddit user “Joshua_Glock” posted a picture of the restaurant’s handwritten Wi-Fi equation this past weekend, but no one has been able to connect to the network yet, First We Feast reported.
The Reddit community has been in a frenzy trying to solve the equation.
“This looks a lot like a summation of a binomial probability density function,” one Reddit user wrote. “I strongly doubt the divider between N/m should even be there.”
After receiving more than 400 comments, Reddit user “Joshua_Glock” claimed to have revisited the restaurant again and again to test out new suggestions.
This isn’t the first time a restaurant has stumped its customers with a math equation.
