Divide Emoji

➗ is the Heavy Division Sign. The symbol itself is called an obelus, and it has the strangest backstory of any math emoji. Before it was a division operator, it was a proofreading mark. The Greek word ὀβελός (obelós) literally meant "sharpened stick" or "spit" (as in the cooking implement), and the Homeric scholar Zenodotus invented the mark around 250 BCE to flag passages in ancient manuscripts that he suspected were fake or corrupted. "This verse is doubtful" was its original meaning. That is to say: the math emoji that marks dividing one number by another started life meaning "this might be wrong."

It took almost 2,000 years for the obelus to become a math symbol. Swiss mathematician Johann Rahn used ÷ for division in his 1659 book Teutsche Algebra, published with editing help from English mathematician John Pell. Some historians think Pell, not Rahn, is actually responsible for the symbol's mathematical adoption. Before 1659, European mathematicians had used the same ÷ shape for subtraction, which is exactly the kind of notational confusion that later drove Gottfried Leibniz to propose the colon (:) for division in 1684.

The colon won across most of continental Europe. Germany, Russia, Ukraine, and Sweden all teach division as a : b rather than a ÷ b. The obelus stuck in English-speaking countries, especially the US and UK. The ISO 80000-2 international standard for math notation in science and engineering actually says ÷ "should not be used" and recommends the solidus (/) or colon instead. Anglophone school textbooks ignore the standard, which is why ÷ is still the first division symbol every American and British kid learns.

In Unicode, ➗ is U+2797 HEAVY DIVISION SIGN, added to the Dingbats block imported from Hermann Zapf's 1978 ITC Zapf Dingbats typeface. Unicode 6.0 (October 2010) gave it emoji presentation, and Emoji 1.0 in 2015 added color. The shape (horizontal bar with dots above and below) was reportedly chosen to suggest the fraction bar with its numerator and denominator reduced to dots. It's the only emoji whose geometry is literally a pedagogical mnemonic.

Then in March 2017, Ed Sheeran released ÷ (Divide)), the most commercially successful album of his math-symbol series. It sold 6.1 million copies globally in 2017 alone, became the year's bestselling album worldwide, and made ÷ the emoji that a generation of Sheeran fans associates with "Shape of You" and "Perfect" rather than long division homework.

➗ sits in the middle of the math emoji family for search volume. Not as ignored as ➖, not as universally loved as ➕. People reach for it in four specific contexts.

Splitting a bill or resource. The flagship figurative use. "Let's ➗ the Uber" or "We'll ➗ the groceries" reads instantly. Group chat culture on iMessage and WhatsApp leans on it.

Math content and education. TikTok math teachers, homework-help threads, and study accounts use ➗ unambiguously. Most educational content that involves arithmetic also involves ➗ for genuine long division.

"Divided" as rhetoric. Political posts, cultural critique, sports rivalries. "The country is ➗" or "fanbase ➗" as visual shorthand for "split down the middle." Carries more tension than ➖.

Ed Sheeran fan posts. ÷ is the title of his 2017 album, and his biggest single ("Shape of You") came from it. Fan accounts tag Divide-era posts with ➗ the way Plus-era posts get ➕.

The emoji that ➗ does not do well is emotional loss. Unlike ➖, which can occasionally express absence, ➗ always suggests active splitting. Two parties, two sides, two halves. If you want "loss," use ➖ or 💔. If you want "partition," use ➗.

One quirk: ➗ is one of the harder math emojis to type. On most keyboards there's no direct shortcut, and people often type /instead, which is why search volume underrepresents actual conceptual usage.

The obelus is older than arithmetic. Around 250 BCE, the Greek scholar Zenodotus of Ephesus, working at the Library of Alexandria, needed a way to flag passages in Homeric manuscripts that looked forged or corrupted. He invented a system of marginal symbols, and one of them was a horizontal stroke (ὀβελός, "little spit," from the Greek word for a skewer or cooking spit) that meant "this passage is doubtful." Over the next two millennia, the mark evolved through medieval manuscript tradition, sometimes becoming a dagger (†) used to flag notes or mark the dead.

In 1659, Swiss mathematician Johann Rahn published Teutsche Algebra in Zurich. The book was unusual for being printed entirely in the vernacular German ("Teutsche") rather than Latin, and was edited in places by English mathematician John Pell, who had met Rahn while serving as a diplomat in Switzerland. Somewhere in that collaboration, ÷ became the symbol for division. Some historians credit Pell with the choice. Before 1659, the same ÷ shape had been used by some European mathematicians for subtraction, which contributed to centuries of notational chaos.

Gottfried Leibniz wasn't having it. In his 1684 paper in Acta Eruditorum, Leibniz proposed using the colon (:) for division, because he felt the same symbol should cover both ratio and division (a:b reads as both "a to b" and "a divided by b"). The colon conquered continental Europe: Germany, Russia, Ukraine, and Sweden all teach division with the colon. English-speaking countries kept the obelus.

The divergence is still formalized. The ISO 80000-2 international standard for math notation in science says the ÷ sign "should not be used" and recommends the solidus (/) or the colon instead. Anglophone textbooks ignore the ISO recommendation, which is why American and British schoolchildren learn ÷ while their German peers never see it.

Hermann Zapf's 1978 ITC Zapf Dingbats included a heavy division glyph for typesetters. Unicode 1.1 imported the Dingbats block in June 1993 and assigned U+2797 HEAVY DIVISION SIGN. Unicode 6.0 (October 2010) added emoji presentation, and Emoji 1.0 (2015) brought color rendering.

On 3 March 2017, Ed Sheeran released ÷ (Divide)). It sold 672,000 copies in the UK in its first week, the fastest-selling album by a male artist in UK chart history, and the third-highest opening-week figure ever behind Adele's 25 and Oasis' Be Here Now. The same week, all 16 tracks on Divide entered the UK top 20 and 9 of them simultaneously occupied the UK top 10, breaking a record previously held by Calvin Harris. Globally, Divide became the bestselling album of 2017 at 6.1 million copies. "Shape of You" became the most-streamed song on Spotify in 24 hours on release day. "Perfect" was the 2017 UK Christmas #1. The success made ÷ the math emoji that Ed Sheeran fans type most, third in a series of math-album covers that Sheeran would continue with = (2021) and − (2023).
