About
9+10=21 is an incorrect answer to a math problem, which was first spoken online in a Vine video. The video, also known as "What's Nine Plus Ten," quickly became a fad within the Vine community, leading to remixes and other parody, and later spreading to various other internet communities. In Summer 2019, the video saw a resurgence in popularity on Instagram, Twitter and iFunny.
Origin
On June 22nd, 2013, Vine[3] user @DREHUPEMSU @WESTROSECRAN published the original video.[14] Within eight years, the post received more than 30 million loops, 707,000 likes and 605,000 revines (mirror below).[5] In the Vine, a man talks to a boy and claims that he is stupid. After the boy replies that he isn't, then the man asks him, "What's 9+10?" to which the boy answers "21." The man then reaffirms his statement.
- You stupid.
- No, I'm not.
- What's nine plus ten?
- Twenty one.
- You stupid.
Spread
The first known remix of the Vine[18] was posted by user BRUH, where it received over 7.14 million loops, 185,000 likes, and 145,000 revines; another remix was posted a few days later.
Although the original Vine was deleted, the video was re-uploaded to YouTube on July 7th, 2014, by Alondra Morelos,[1] and then again on July 9th by YouTuber Shadow Subscribe (seen below).[2] By December 14, 2014, Morelos' upload had received over 5.7 million views and 37,000 likes, and Shadow's upload had received 3.7 million views and 28,000 likes.
Later, on August 29th, YouTube user SwiftStar352 uploaded[4] a song featuring audio from the Vine (seen below) remixed with "Hot Nigga" by rap star Bobby Shmurda, which was one of the nation's top songs at the time. The song reached 14.6 million views and 108,000 likes by December 2014. It has since been deleted, but a re-upload by Simply Boggsy has received over 390,000 views as of April 2016.
The child in the video, whose identity remains unknown, has often been referred to as "The 21 Kid."
Runaway Hoax
On October 13th, the parody website Huzlers released a hoax article detailing how the child had run away.[6] The article noted that the child had left a goodbye note.
The child, whose real name is Habeeb Cisse, ran away from his home Saturday night and is currently being searched for throughout the whole Baltimore area. Authorities say the child left a goodbye note in his bedroom that read:
“I tired of everyone lafing(laughing) at me, I running away forever now, if yu(you) want to find me the only clue I leaving is 21”
Posts on several message boards, including IGN, indicated that some people fell for the hoax. A complimentary YouTube video was released by the user Franklin Clinton and received over 650,000 views as of April 2016. It is proven by YouTuber WavyWebSurf[15] that this is the 21 kid because this video was originally uploaded on DREHUPEMSU's Vine page
On October 3rd, 2020, WavyWebSurf posted a video deep-diving into the hoax, gaining over 3.7 million views in a year (shown below).
2019 Resurgence
In Summer 2019, memes based on the Vine regained popularity on Twitter, iFunny and Instagram. Before April 4th, an unknown user posted a Not Funny, Didn't Laugh video featuring a still image from the Vine. On April 4th, 2019, the video was reuploaded to YouTube where it gained over 28,100 views within four months (shown below).[7] On June 10th, 2019, YouTube user Bleu Chicken reuploaded an Awesome, He Finally meme based on the video made by an unknown author (shown below, right).[8]
In the following month, the Vine gained further spread on iFunny, Twitter and on Instagram. On July 1st, 2019, Twitter user @Timotainment[9] posted a "Not Funny, Didn't Laugh" edit of the Vine featuring Donkey Kong, with the video accumulating over 413,000 views in one month, and the tweet gaining over 14,500 retweets and 46,100 likes.[8]
