Hebrew numeral

The Hebrew numeral system is a ciphered numeral system where letters of the Hebrew alphabet are assigned numerical values. The first ten letters represent numbers 1 through 10, the next eight represent 20 through 90 in increments of ten, and the final four letters represent 100, 200, 300, and 400. This system differs from modern Hindu-Arabic numerals, which are place-value systems. While Hebrew numerals were historically used for calculations, their primary modern application is in gematria, a method of exegesis used by Kabbalists to derive mystical insights from sacred texts.123
