Numerology uses numbers as a key to human behaviour. Numerology is not a complete science it is just a branch of the predictive sciences. For a numerologist there are only 9 numbers from which all calculations of the material world are made.
Sun = 1
Moon= 2
Jupiter = 3
Rahu = 4
Mercury = 5
Venus = 6
Ketu = 7
Saturn = 8
Mars = 9
All numbers beyond 9 are repetitions. The number 10 is not a whole number, it is simply a 1 with a 0 etc.
In Vedic numerology we use 3 basic concepts;
Psychic no= representing self image
Destiny no= pertaining to karma and how others perceive you
Name no= Social/ professional life.
Together these three numbers reveal info about your temperament, intelligence, sexuality, finances and health.
