If you've ever looked at an Arabic text and felt confused by numbers that look nothing like the digits 0–9 you use every day, you're not alone. What most people don't realize is that the familiar digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 — used across the English-speaking world — are themselves called Arabic numerals. Yet when you open an Arabic newspaper or read a Quran printed in the Middle East, the numbers look entirely different.
This is because there are two distinct Arabic numeral systems: the Eastern Arabic numerals (used throughout the Arab world and Iran) and the Western Arabic numerals (used globally in mathematics, science, and everyday life in most countries). Understanding the difference between these two systems is essential for anyone learning Arabic or exploring the history of numbers.
In this article, we'll break down both systems, explore their origins, show you how to recognize and read each set of digits, and explain which system is used where. Whether you're a language learner or simply a curious reader, this guide will give you a clear picture of one of history's most fascinating numerical stories.
A Brief History of Arabic Numerals
To understand the split between Eastern and Western Arabic numerals, we need to travel back over a thousand years to medieval Baghdad — the heart of the Islamic Golden Age.
Around the 9th century CE, Arab mathematicians adopted a positional number system from Indian scholars. This system, which used place value and included a symbol for zero, was revolutionary. The great mathematician Al-Khwarizmi (from whose name we get the word algorithm) played a central role in spreading this system throughout the Arab world.
As Arab traders and scholars traveled westward into North Africa and eventually into Europe through Spain and Sicily, they brought this numerical system with them. However, over centuries, the symbols used in the western regions (known as the Maghreb — modern-day Morocco, Algeria, Tunisia, Libya) gradually evolved into a different visual form from those used in the eastern regions (Egypt, the Arabian Peninsula, the Levant, Persia/Iran).
By the time European scholars adopted the system in the 10th–12th centuries, they were learning from the western Arabic tradition — giving us the digits we use today (0–9). Meanwhile, the eastern Arabic world retained its own distinct digit shapes, which descended more directly from the original Indian-influenced forms.
This is why both systems are legitimately called "Arabic numerals" — they share the same ancient origin, even if they look visually different today.
Western Arabic Numerals: The Numbers You Already Know
Western Arabic numerals are the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. These are used almost universally in:
- The English-speaking world
- Europe and the Americas
- East Asia (alongside local numeral systems)
- International science, mathematics, and technology
- Global digital systems and computing
Despite being called "Arabic" numerals in English, most Arabic-speaking countries in the Middle East do not primarily use these for everyday writing. However, they are widely understood throughout the Arab world due to global education and technology.
Western Arabic numerals developed their familiar shapes through centuries of handwritten manuscripts in medieval Europe. The round, flowing forms we know today were standardized through the printing press era.
For English speakers learning Arabic, it's worth noting that knowing 0–9 is not enough to read numbers in Arabic texts — you'll also need to learn the Eastern system.
Eastern Arabic Numerals: The Numbers of the Arab World
Eastern Arabic numerals — sometimes called Hindi-Arabic numerals or Arabic-Indic numerals — are the digit symbols used in most Arabic-speaking countries today, as well as in Persian (Farsi) and Urdu writing systems.
Here is a side-by-side comparison of Eastern Arabic numerals and their Western equivalents:
| Western | Eastern Arabic | Name in Arabic |
|---|---|---|
| 0 | ٠ | صِفْر (Sifr) |
| 1 | ١ | وَاحِد (Wāḥid) |
| 2 | ٢ | اثْنَان (Ithnān) |
| 3 | ٣ | ثَلَاثَة (Thalātha) |
| 4 | ٤ | أَرْبَعَة (Arbaʿa) |
| 5 | ٥ | خَمْسَة (Khamsa) |
| 6 | ٦ | سِتَّة (Sitta) |
| 7 | ٧ | سَبْعَة (Sabʿa) |
| 8 | ٨ | ثَمَانِيَة (Thamāniya) |
| 9 | ٩ | تِسْعَة (Tisʿa) |
At first glance, some Eastern Arabic numerals may look unfamiliar, but a few share visual similarities with their Western counterparts:
- ١ (1) looks like a simple vertical stroke — similar to the Western 1
- ٩ (9) may remind some learners of a reversed 9
- ٤ (4) and ٦ (6) look quite different and require memorization
- ٥ (5) — interestingly — resembles a Western zero (0), which often confuses beginners
Take special care with ٥ (5) and ٠ (0), as mixing them up is one of the most common mistakes for new learners.

Hindi-Arabic Numerals: Why the Extra Name?
You may encounter the term Hindi-Arabic numerals or Hindu-Arabic numerals, and wonder what that means.
This name acknowledges the full historical journey of the number system:
- Hindu mathematicians in ancient India (particularly in the Brahmi script tradition) developed the positional decimal system and the concept of zero.
- Arab scholars adopted and transmitted this system westward, refining and spreading it during the Islamic Golden Age.
- European scholars learned the system from Arab sources, adapting it further into what became Western Arabic numerals.
So "Hindu-Arabic" gives credit to both the Indian origin and the Arab transmission. When people say Hindi-Arabic numerals, they are usually referring to the Eastern Arabic numeral forms (٠١٢٣٤٥٦٧٨٩) — recognizing that these digit shapes are closer to the original Indian-derived symbols.
In Iran, these numerals are sometimes called simply Persian numerals or Farsi numerals, and there are slight variations in a few digit shapes (particularly 4, 5, and 6) between the Arabic and Persian versions of the Eastern system.
Where Are Eastern Arabic Numerals Used Today?
Eastern Arabic numerals are the standard in several major regions:
Arab World (Middle East):
- Egypt
- Saudi Arabia
- UAE, Kuwait, Qatar, Bahrain, Oman
- Jordan, Syria, Lebanon, Iraq
- Sudan, Yemen
Iran: Persian numerals (a slight variant of Eastern Arabic)
Pakistan: Urdu uses a variant of Eastern Arabic numerals
Afghanistan: Pashto and Dari texts use Eastern Arabic/Persian numerals
Interestingly, North Africa (Morocco, Algeria, Tunisia) historically used Western Arabic numerals more commonly even in Arabic texts — a legacy of their closer contact with European mathematical traditions. Today, many educated people in these countries use both systems fluidly.
In digital contexts, Western Arabic numerals (0–9) are increasingly common even in Arab countries, especially in texting, social media, and international communication. However, official documents, newspapers, books, and religious texts in the Arab world typically use Eastern Arabic numerals.
How Numbers Are Written in Arabic Text
Arabic is written from right to left, which naturally raises the question: are numbers also written right to left?
The answer is nuanced:
- Arabic text flows right to left.
- Numbers within Arabic text are written with the digits in left-to-right order (the same directional order as in English), even though they appear embedded in a right-to-left sentence.
So in a sentence like:
عندي ٣ كتب (ʿIndī 3 kutub — "I have 3 books")
The number ٣ is a single digit, so direction doesn't affect it. But a larger number like ١٢٣ (123) reads left-to-right: ١ is the hundreds digit, ٢ is the tens digit, and ٣ is the units digit — just as in English.
This can feel counterintuitive, but it becomes natural with practice. For a detailed look at how Arabic numbers work with pronunciation, check out our guide to Arabic Numbers 1-100.
Tips for Learning Eastern Arabic Numerals
Learning a new set of digit symbols may feel daunting, but Eastern Arabic numerals are actually one of the quickest parts of Arabic to master. Here are some practical tips:
1. Use Visual Mnemonics
Create memory associations:
- ٣ (3) looks like a backwards "3" — mirror image memory trick
- ٥ (5) looks like a circle — remember "5 is round, not zero!"
- ٧ (7) has a hook — "7 goes fishing with a hook"
2. Practice with Real Text
Find Arabic newspapers, menus, receipts, or websites and identify numbers in context. Real-world practice accelerates memorization far faster than flashcards alone.
3. Write Them Out Repeatedly
Just like learning the Arabic alphabet, repetitive handwriting practice builds muscle memory for recognizing and producing digit shapes.
4. Use Dates and Phone Numbers
Practice writing today's date or phone numbers using Eastern Arabic numerals. Contextual practice makes the digits feel immediately useful.
5. Start with 0–9, Then Scale Up
Once you know all ten digits, reading any number — no matter how large — is simply a matter of combining what you already know. Visit the Arabic numbers page to practice with examples up to the thousands.
Arabic Numeral Systems and Language Learning
Understanding Arabic numeral systems is a small but important part of becoming literate in Arabic. When you pick up an Arabic book, sign, or document, being able to read dates, prices, page numbers, and statistics gives you an enormous practical advantage.
Numbers also connect to broader aspects of Arabic grammar. For example, Arabic has complex agreement rules between numbers and nouns — singular, dual, plural, masculine, and feminine forms all interact with numbers in fascinating ways. This is explored in depth in our Arabic Grammar Basics guide.
