A simple example
11 naturally leads to 2
If your date reduces to 11, that is Justice. Reducing 1 + 1 gives 2, The High Priestess. The supported pair is therefore 11 → 2.
If the arithmetic reaches one digit
The pair is still shown
This system maps a final single digit back to its associated 10–18 Personality Card. A final 4 is displayed as 13 → 4, Death / The Emperor. It does not become a one-card result.
The one exception
19 produces three cards
A final 19 continues through 10 to 1, producing The Sun / Wheel of Fortune / The Magician. It is the calculator’s only three-card sequence.
How to read the relationship
Two lenses on one symbolic pattern
The higher number is commonly used as a Personality Card lens, while the smaller reduced number is used as a Soul Card lens. These are reflection prompts, not diagnoses or fixed personality labels. See Personality Card vs Soul Card for a side-by-side explanation.
