Pythagorean Square
The psychomatrix, or "Pythagorean Square," is a 3×3 table filled with digits from the birth date. Each cell corresponds to a specific quality, and the number of digits shows how strongly it is expressed. The calculation follows Alexandrov's method.

The "Pythagorean Square" method (psychomatrix) is a modern, Russian-language method associated with A. F. Alexandrov (1990s books). No direct historical continuity with the ancient Pythagorean school has been established.
How the calculator works
Four working numbers are derived from the birth date. The first is the sum of all digits in the date taken as a whole. Let us use an example: 15.08.1990. Adding each digit: 1 + 5 + 0 + 8 + 1 + 9 + 9 + 0 = 33. This is the first working number — the "goal," what a person strives for. The second is the sum of the first number's digits: 3 + 3 = 6. This is the "innate foundation" — what is laid down from birth. The third number is calculated differently: the first number minus twice the leading digit of the birth day. For the 15th, the leading digit is 1, so: 33 − 2 × 1 = 31. The day is taken without a leading zero: 5, not 05. The third number represents "acquired qualities" that develop throughout life. The fourth is the sum of the third number's digits: 3 + 1 = 4. This is the "result" — what a person arrives at in maturity. If the second or fourth number equals 10, 11, or 12, in Alexandrov's method they are not reduced to a single digit — these are "governing numbers" that strengthen the influence of the corresponding cells in the square.
The resulting digits are distributed across the cells of the 3×3 square, each corresponding to a specific quality. In Pythagorean numerology, these are, for example: 1 — character and willpower, 2 — energy, 3 — interest and talent, 4 — health, 5 — logic and intuition, 6 — work and mind, 7 — luck and talent, 8 — duty and responsibility, 9 — memory and mind. The digits of the birth date and all four working numbers are placed into their respective cells. If a digit matches the cell number, it "lands" there; if no such digit exists, the cell remains empty. The interpretation depends on the number of digits in a cell: empty — the quality is not innate and needs to be developed; one digit — weak but sufficient expression; two digits — normal, moderately developed quality; three or more — strongly expressed characteristic.
