The sum 87: what it means
The digit sum of a number, as Thai เลขศาสตร์ reads it. DUANGLY takes these meanings from published ตำรา and says every time which text each one came from.
How it is worked out
ผลรวม is every digit of the number added together, which means it cannot see order: numbers built from the same digits in a different arrangement always come to the same total. That is why the sum carries less weight than the คู่เลข in our formula.
No Thai mobile number adds up to this. They begin 06, 08 or 09, which puts every possible total between 6 and 81. This one is in the table for completeness.
How far to trust it
No text we checked writes about this one. We call it neutral, and it moves the score neither up nor down. Nobody having written about it is not a verdict either way.
