Root Numbers

Reduces a number, or a word in Pythagorean letter values (A–I, J–R and S–Z counted 1–9), to one digit by repeated digit sums, flagging 11, 22 and 33; reduces a date digit by digit and as the life path; and looks up repeating “angel numbers”. The root equals the remainder on division by 9 (9 if none). Angel numbers come from Doreen Virtue and Lynnette Brown (2005).
