Personality Number

Computed from the consonants of your full birth name; said to describe the first impression you give.

The consonants are summed and reduced. Together, the Soul Urge (vowels) and Personality (consonants) sums add up to the Expression (all letters) sum — a tidy arithmetic property, not evidence of anything. Both systems are shown because they disagree.

Not: Not how people actually perceive you — that is set by your behaviour, not your spelling.

Convention only, and dependent on name and system choice.
