[1] There was no notation for zero in the old system, and the numeric values for individual letters were added together.
In contemporary writing, Armenian numerals are used more or less like Roman numerals in modern English, e.g. Գարեգին Բ. means Garegin II and Գ. գլուխ means Chapter III (as a headline).
As in Hebrew and ancient notation, in Armenian numerals distinct symbols represent multiples of powers of 10, from 1 to 9, 10 to 90, 100 to 900, 1,000 to 9,000, and 10,000 and 20,000.
A number is written from left to right, composed from at most one of these symbols for each power of 10, arranged in descending order by magnitude.
This is similar to Roman numerals, where a line over a character means multiplying the corresponding value by 1,000.
