Use simple charts to convert names into numbers. Different numerology systems use different charts. The easiest way is to use the number 1 for the letter A, the number 2 for the letter B, and so on. Believers in numerology usually use the names given by parents when a person is born. They think the name they take at birth is much more important than the nickname, the name they take after marriage or the name they change later. In order to determine a person's number, numerologists usually choose the corresponding numbers from the chart and add them up. If the result is two or more digits, add these digits together and follow this method until you finally get a digit. For example, in the name of harry james potter, the letters in Harry add up to 34, James is 12, and Potter is 3 1, 34+ 12+3 1=77. In some systems, 77 may be a dominant number, but usually people will add 7 and 7 to get 14, and then 1+4=5. So, 5 is the number of harry james potter. In addition, believers in numerology use charts to analyze the relationship between numbers and letters. These charts are similar to constellation charts, which can expand other meaning on the basis of digital reading. But whether the system used by numerology believers is complex or simple, it is just like astrology in the final analysis.
