Calculating a lucky number for Manfried
The lucky number for Manfried (or any other name) is calculated by using a special table which gives a numeric value to each letter of the alphabet. The table we used is derived from the Kabbalah and used by Hebrew and Arab mystics.
Here are the letters of the roman alphabet and their values:
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
| 1 | 2 | 3 | 4 | 5 | 8 | 3 | 5 | 1 | 1 | 2 | 3 | 4 | 5 | 7 | 8 | 1 | 2 | 3 | 4 | 6 | 6 | 6 | 5 | 1 | 7 |
So the numbers for each letter of Manfried are:
| M | a | n | f | r | i | e | d |
| 4 | 1 | 5 | 8 | 2 | 1 | 5 | 4 |
First we add the digits of all the letters: 4+1+5+8+2+1+5+4 = 30
Which is still more than one digit
so we add the digits of 30: 3+0 = 3
Which gives Manfried a lucky number of three!
