Which number is the premises number?
The unit as written, letters on the Chaldean table and digits summed: 7B is 7 + 2. Practitioners count only the unit; street numbers and PIN codes are excluded. The floor, building and street layers are NumeroPandit's extension and carry half the weight of the unit between them.

This part is worked out by the calculators: open the calculator.
What each floor reads
Practitioners give the floors readings from principal-led (1) through advisory with a caution (2), social and creative (3), systems with a caution (4), movement and sales (5), comfort and design (6), analysis and law (7), accumulation friendly only to Origin number 5 (8) and restructuring, likewise (9). The ground floor carries no digit.
The blanket caution on 2, 4 and 8
A unit on 2, 4 or 8 caps the whole reading at 55, following the practitioners' general caution on those digits. Compounds 13, 16, 17, 19, 26, 28 and 43 cost ten points. Rented premises are read against the Origin number and owned premises against the Master number in one practitioner's rule; NumeroPandit reads both against the Origin number and says so.
What to do about a weak unit
Match the trade to the digit before moving: a 4 unit favours repairs and technology, a 5 convenience and courier, a 6 salons and cafes. Then run the Kua reading for the desk direction, which is in the Blueprint.
