In the era of online education, teachers are finding it close to impossible to hold classes for students in an interesting and enjoyable way. One teacher from Taiwan, however, have come up with the most hardcore way to teach calculus: post the videos on Pornhub.

Fantasies with teachers is one of the main kinks on the adult streaming platform. A clip usually starts with a lesson before the learning session goes south. However, a Taiwanese mathematician on the site solves calculus without stripping down in the process.

Changshu, going by the handle changshumath666, has taken his teaching methods to the extreme by uploading over 200 videos of him teaching calculus on the pornographic website.

Changshu holds a master’s degree in mathematics and has been teaching both in Taiwanese schools and online for the past 15 years. Talking to Mel Magazine, he originally tried uploading his teaching videos on his YouTube channel, but he didn’t do as well as he hoped he would in terms of engagements.

“Since very few people teach math on adult video platforms, and since there are so many people who watch videos on them, I thought that if I uploaded my videos there, a lot of people would see them,” said Changshu.

Thus, in 2020, he thought of migrating to the mature video website. Even though his more than 6,500 subscribers on PornHub is lesser than his 22,800 subscribers over at YouTube, he still gets more video views on the unconventional platform. Racking up more than 1.7 million views. His “model rank” puts him at 1,684th place.

He has also tried to take his calculus videos to other pornographic websites but he says that “those platforms know which kinds of videos are adult and which aren’t, and they forbid them.”

In a recent Ask Me Anything on Reddit, the college math teacher shared some insights on why he chose an unusual platform for his study content. “We like to be special and impressive. Moreover, education shouldn’t be that traditional! Learning can be everywhere,” said Chang-Hsu.

His videos have recently embraced naughtiness. His team has also brought in known adult entertainers to collaborate on some content. But he claims his channel will never see him strip down.

Whether people visit Pornhub to learn calculus or to drop by his channel for a chuckle, Changshu doesn’t mind: “People may not be interested in my videos, but they’ll all know there’s a teacher who teaches calculus on an adult video platform. I didn’t want to teach math on Pornhub. I wanted to let the world know that I’m a teacher from Taiwan who can teach calculus well.”
