"Excuse me Professor" Star said raising her hand "I just read this out of the book" she said then looked in her book and read what it said... Quote:
Like astrology, arithmancy claims to offer practitioners a system for determining favorable and unfavorable days for any individual. As a general rule, favorable days are supposed to be those that correspond to a person's character number. An "eight" personality, for example, would be advised to schedule important events like starting a business or getting married so that they occur on the 8th, 17th, or 26th of the month (each of which reduces to 8).
"I don't get this... I do not see why they say the reduce down to 8, because 17 is not divisible by 8... could you explain this?" she asked.
