Hebrew numerals: alphabetic numbering, values, and uses
Alphabetic numeral system that assigns numeric values to letters of the Hebrew alphabet; used historically and today for dates, chapters, gematria and liturgical numbering.
The Hebrew numerals form an alphabetic, quasi‑decimal system in which letters of the Hebrew script stand for numbers rather than a separate set of digits. This approach is one example of alphabetic numeration found in other traditions (alphabetic numeral systems), and it relies on the letters of the Hebrew alphabet to indicate value. There is no symbol for zero: numbers are written additively by combining letters whose values sum to the desired total.

Basic structure and common values
Values are assigned in three groups. Units use the first nine letters for 1–9; tens use the next nine for 10–90; hundreds use further letters for 100–400. Typical assignments include (selected examples):
- Units: Alef = 1, Bet = 2, ... Yod = 10
- Tens: Kaf = 20, Lamed = 30, ... Tzadi = 90
- Hundreds: Qof = 100, Resh = 200, Shin = 300, Tav = 400
Higher numbers are made by addition (for example 23 = 20 + 3). For thousands the same letters may be used with additional notation or by repeating marks; some traditions also extend values using the so‑called final forms for 500–900.
Notation, punctuation and variants
Hebrew numerals are frequently marked to distinguish them from words. A single mark (geresh, similar to an apostrophe) is placed after a single‑letter numeral, while a double mark (gershayim) precedes the last letter of a multi‑letter numeral. Different communities developed variants: some treat final‑form letters as distinct numerals for 500–900, others form larger values by combining letters or using thousands signs.
History, uses and cultural notes
The system has ancient origins and has been used in manuscripts, inscriptions, calendars and religious texts. Today it commonly appears in Jewish calendar dates, chapter and verse numbering in liturgical and rabbinic works, and on tombstones. Beyond practical counting, letter values underpin the practice of gematria, which explores numerical relationships among words and phrases.
Notable practices and distinctions
Some conventions arise from religious sensitivity: for example, the numbers 15 and 16 are usually written as ט"ו (9+6) and ט"ז (9+7) rather than as the sequences that would form the divine name. The system differs from positional decimal systems (like Arabic numerals) because values are additive and there is no place value or zero. Despite that, Hebrew numerals remain a living script feature, combining linguistic and numeric functions in Jewish culture.
