Ge'ez uses a system of ones and tens comparable to the Hebrew, Arabic abjad and Greek numerals, but unlike these systems, rather than giving numeric values to letters, it has digits derived from the Coptic letter-numbers:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | |
|---|---|---|---|---|---|---|---|---|---|
| × 1 | ፩ | ፪ | ፫ | ፬ | ፭ | ፮ | ፯ | ፰ | ፱ |
| × 10 | ፲ | ፳ | ፴ | ፵ | ፶ | ፷ | ፸ | ፹ | ፺ |
| × 100 | ፻ | ||||||||
| × 10.000 | ፼ | ||||||||
It has been claimed by Georges Ifrah that Ethiopian numerals were borrowed from the Greek numerals in the fourth century CE, but this has been disputed by Ayele Bekerie of Cornell University, who claims that the Ethiopian system was developed independently.
