8=23. However in real numerology  the number would be added as 3+1+8, equaling 12. The sum would then  be added again to create a single digit, 1+2 = 3. 3 would be the  significant number here, and there are many sources on the Internet  or in various numerology books that would define what significance  that number would hold for the individual. As another example, the  address of the bookstore would have more credibility as their sum  does equal 23 (5+9+9=23). But another step would need to be taken to  convert the sum into a single digit (2+3 = 5). Finally, birthdays  and other notable dates in numerology are always factored with the  year. Following the formula of February 3 (2/3 = 23) would be  inaccurate. But December 12, 1975 (12/12/1975 = 1+2+1+2+1+9+7+5 = 28  = 2+8 = 10 = 1+0 = 1. Therefore, for a person born on this date, the  number 1 should be the most significant.
