Algorithm

Numbers in the Armenian numeral system are obtained by simple addition. Armenian numerals are written left-to-right (as in the Armenian language). Although the order of the numerals is irrelevant since only addition is performed, the convention is to write them in decreasing order of value.


Samples

* = 1975 = 1000 + 900 + 70 + 5 * = 2222 = 2000 + 200 + 20 + 2 * = 2004 = 2000 + 4 * = 120 = 100 + 20 * = 50 To write numbers greater than 9999, it is necessary to have numerals with values greater than 9000. This is done by drawing a line over them, indicating their value is to be multiplied by 10000. This is similar to Roman numerals, where a line over a character means multiplying the corresponding value by 1000. Examples: * Ա = 10000 * Ջ = 9000000 * ՌՃԽԳ{{lang, hy, ՌՄԾԵ = 11431255
