Arabic numerals: why we write with them but read them differently than Arabs do

A surprising fact to start with. The digits 1, 2, 3 used by literally the whole world — from a Japanese calculator to an American bank — are called "Arabic." That's how they're labelled in maths textbooks. And yet here's the paradox: you land in Cairo or Dubai, open a menu, glance at a price tag — and there isn't a single familiar digit in sight. In their place, a scattering of mysterious marks: ٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩.

So how did that happen? Why do "Arabic" numerals look nothing like Arabic, while the real Arabic ones read like a secret code to us? Let's lay this historical curiosity out step by step. And along the way we'll see why, for a beginner, numbers are perhaps the easiest and most useful thing you can learn in Arabic in your very first week. Spoiler: they take one evening, and they pay off for the whole trip.

Two systems, and both are "Arabic"

The story here is better than any detective novel. Positional decimal notation — the kind where a mark's value depends on its place (ones, tens, hundreds) — was born in India. From there it was taken up and developed by the mathematicians of the Arab golden age. In the 9th century al-Khwarizmi wrote a treatise on Indian reckoning: it's from his name, Latinised as Algoritmi, that we get the word "algorithm," and from the title of another of his works, al-jabr, the word "algebra." A whole layer of mathematics grew out of those books.

The digits reached Europe not straight from India but through the Arab world — via Spain and works such as the "Book of Calculation" by Leonardo of Pisa, better known as Fibonacci, in the early 13th century. Europeans received them, so to speak, from Arab hands — and called them Arabic. The Arabs themselves, remembering the original source, call these familiar marks Arabic-Indic, that is, "Indian numerals." So the very same symbols are Arabic to us and Indian to an Arab. It all depends on which direction they travelled to reach you.

But in everyday writing across the eastern Arab world — in Egypt, the Gulf states, Sudan — a different set of shapes is used: the Eastern Arabic numerals. Here's the full correspondence, worth printing and pinning up where you can see it:

And one more detail for good measure. The word Arabs use for zero sounds like "sifr" (emptiness, nothing). Through medieval Latin it spread across the European languages in two directions at once: it gave us both "zero" and "cipher." So the very idea of a "cipher" is a direct Arabic trophy, even though we never think about it while dialling a phone number.

The direction trap: line goes left, numbers go right

Here's the one thing you'll have to adjust to separately with numbers. Arabic text, as everyone knows, runs right to left. But numbers inside it are written and read left to right — in exactly the order you already use. In other words, a single line comfortably holds two opposite directions at once.

Picture a price tag or a model year: the letters around it crawl right to left, while the number ٢٠٢٦ itself you read the usual way, left to right, starting from the highest place value. At first this bends the brain: your eye leads the line one way, then hits the number and seems to stumble and flip for a second. But precisely because the order of the digits matches ours, getting used to it takes only a few days. A phone number, a date, the total on a receipt — you'll read them correctly on the first try; you just have to not be spooked by the marks themselves. That, by the way, is a nice break for a beginner: while you're retraining your eye to move right to left for words, numbers need no retraining at all.

How to learn the Eastern digits in a single evening

Good news: there are only ten, and half of them are recognised instantly. Give your eye a couple of anchors and it's done.

• ١ (1) — a vertical stroke, exactly our "one."
• ٩ (9) — almost our nine, with a loop on top and a little tail.
• ٢ and ٣ — hook-like squiggles; the "three" has one more tooth than the "two," which is neat and logical.
• ٧ (7) — a sharp tick, much like the Latin "V."

And now three classic traps that trip up every other tourist. Remember them and you won't overpay at the market:

• ٠ (0) — is simply a dot. Yes, the Arabic zero is a tiny dot.
• ٥ (5) — while the little circle that looks painfully like our zero actually means five. A round mark in Arabic is a five, not a zero. The number-one beginner trap.
• ٦ (6) — looks like our seven, and vice versa. Don't mix up six and seven.

The way to memorise them is simple and almost playful: take your own phone number and today's date and rewrite them in Eastern digits. Then a price on any product, a flat number, a birth year. Twenty minutes of this "handwriting practice" and your hand and eye grab all ten marks more firmly than any cramming could. By morning you're reading price tags.

Numbers out loud: where haggling at the market begins

Writing is half the job; the other half is spoken aloud. Counting starts with three words, and they'll serve you on day one: واحد (wAhid — "one"), اثنين (itnEyn — "two"), ثلاثة (talAta — "three"). Add a short "how much?" — in Egyptian that's bikAm — and you're already haggling: you asked the price, heard a number, held up your fingers, knocked off a coin or two. Classic Eastern market, where bargaining is not really about money but about respect and the sheer pleasure of the exchange.

Do the dialects differ in counting? Only a touch, and mostly in pronunciation rather than the words themselves. Take "three" — ثلاثة — which in Egypt sounds soft, "talAta": locals usually turn the interdental sound into a plain "t." In the more conservative pronunciation of the Gulf that same interdental hint is often kept. But these are nuances that won't stop anyone from understanding you: the numbers themselves are recognised by ear across the whole Arab world without trouble. So there's no need to learn two "different counts" — the basic numerals are almost shared.

Numbers are the first thing you actually "read" in an Arab country: a price tag, a bus, the number on a door. With them the abstract "squiggles" suddenly turn into a signal you understand — and it's from that small success that our reading course begins, where letters and numbers both start from absolute zero.

Why a beginner needs this right now

You can put off letters and grammar for a while, but numbers catch up with you literally at passport control. The gate number, the flight time, the fare on a taxi meter, the price of a bunch of bananas at the market, the date on an entry ticket, the floor in a lift, the total on a cafe receipt — all of it is Eastern Arabic numerals, and all of it shows up in the very first hours of a trip. Someone who knows them instantly stops being helpless: they read the price themselves, check their change themselves, find the right bus themselves. And that, believe me, gives far more confidence than a dozen memorised phrases.

That's exactly why numbers make the ideal first victory. They deliver a fast, tangible result: invest an evening, and you're already reading the real world around you. And that taste of success is a great push to keep going — on to letters and words.

In short: what to remember

1. Our digits are what Arabs call Arabic-Indic; Egypt and the Gulf use the Eastern Arabic set ٠–٩.
2. Text runs right to left, but numbers run left to right. That's the one "double direction" you adjust to separately.
3. A few marks are deceptive: ٠ is a zero-dot, ٥ is a five (not a zero!), and ٦ looks like our seven.
4. Learning ٠–٩ really does take one evening: rewrite your phone number, a date and a couple of prices in these marks.
5. Start counting with wAhid — itnEyn — talAta, add "bikAm?" and you're already bargaining at the market.

If this little tour hooked you, everything from here falls into place on its own. In our free "Arabic Reading & Writing" course, numbers and letters both begin from absolute zero, in calm steps and without fear: first you recognise the marks, then you build your first words out of them, and within a couple of weeks you're reading real price tags and signs aloud. Start with the numbers today — this is that rare case where a single evening of work is visible to the naked eye at your very first Arab market.
