Letter Table

The Pythagorean table is based on a simple principle: letters receive numbers 1–9 in alphabetical order, and the cycle repeats. Latin alphabet: A = 1, B = 2 … I = 9, then J = 1, K = 2 … R = 9, S = 1 … Z = 8. Each letter maps to exactly one number, with no gaps. The Chaldean table uses values 1–8 assigned by sound vibration, not by position in the alphabet: for example, F = 8, O = 7, A = 1. The number 9 is considered sacred and is not used. The key difference: the Pythagorean system is positional (letter → number by order), while the Chaldean is phonetic (letter → number by sound). Different systems produce different results for the same word. The sum of letters is reduced to a single digit 1–9; master numbers 11, 22, and 33 are not reduced. For Russian words, passport transliteration (GOST R 52535.1-2006 / ICAO) is applied before calculation — Cyrillic is converted to Latin using the standard scheme.

Full tables are published on the school pages: Pythagorean numerology and Chaldean numerology. To use the table: enter a word in Latin (or Cyrillic — the system transliterates automatically), and the calculator shows the value in both systems with a letter-by-letter breakdown. Important: the Chaldean table is not an ancient tradition but a 20th-century reconstruction (Cheiro / William John Warner). Different authors offer slightly different letter arrangements by vibration, and the site uses one of the widely adopted versions.
