Calculate Your Expression Number
Durée estimée : 5 min
Use the exact name as it appears on your birth certificate, with all first names. Example: Marie Claire Dupont.
Use the Pythagorean table: A=1, B=2, C=3... I=9, then J=1, K=2... R=9, then S=1... Example: M=4, A=1, R=9, I=9, E=5.
Add all the digits obtained for each letter of the full name. Marie Claire Dupont = 4+1+9+9+5+3+3+1+9+9+5+4+3+7+6+5+2 = 85.
Reduce the total until you get a digit between 1 and 9, or a master number (11, 22, 33). 85 → 8+5 = 13 → 1+3 = 4.
Your expression number reveals your natural talents and potential. A 4 indicates organizational talents, structure, and reliability.
