Time to see if you can remember your high school proofs and follow along!
Bobobo-bo Bo-bobo may not be the most popular manga/anime in the world, but it has plenty of fans, enough that it was voted the series with the most confusing title ever. And with some of the crazy titles of series Japan has, that’s a pretty high honor.
The series follows an afro-and-sunglasses-donning superhero named Bobobo-bo Bo-bobo who fights an evil hair-stealing empire by using his nose hairs. You know, pretty serious stuff. And what better way to honor such a serious series than by performing some math on it?
Japanese Twitter user @TaroSvs recently posted a picture of their math teacher taking the complex title Bobobo-bo Bo-bobo and simplifying it into more easy-to-understand terms:
▼ “My math teacher has way too much sense. Their factorialization of Bobobo-bo Bobo-bo made me laugh out loud lol.”

Each of the ボ characters in the above image is a “bo,” but it might be a little hard to follow for those unfamiliar with Japanese and/or math that they’ve forgotten about for years now. So let’s go through it together:
▼ First we start out by rearranging the sloppy original title into something cleaner.
We’re assuming the the variables “Bo” and “bo” are the same as well.
▼ Next, we remove a Bo from each parentheses,
and since we take a bo from each we have to square it.
▼ Then we break up the middle section into its component parts…
▼ Then finally we inverse the end section from (1-bo) to -(bo-1)
which allows us to square the matching section and move the minus sign to the start!
And there you have it! So if you ever need to talk about Bobobo-bo Bo-bobo again, don’t go around using its unnecessarily complex title. Use the much simpler title -Bo^2(Bo+1)(Bo-1)^2 instead!
▼ Math has always been a part of -Bo^2(Bo+1)(Bo-1)^2,
like this scene where the hero uses numbers’ own powers against them…
▼ …or here, where they can only cower in fear of the mighty abacus… sandals.

Here’s what Japanese netizens thought of the fictional factorialization:
“This is revolutionary teaching!”
“Not sure what you mean by your teacher having ‘sense,’ but I will say I’m jealous.”
“I could totally see kids taking this down as serious notes.”
“Hey, as long as they’re learning, who cares!”
“I want to take this class lol.”
While you may not be able to take the class yourself, you can still definitely check out -Bo^2(Bo+1)(Bo-1)^2 if you’ve never seen/read it before. It was voted one of the top ten series that will leave you laughing in tears, so get ready to break out some pencils, graph paper, and simplify your life with some poop and duck jokes!
