Introduction to arithmetic divination

The series of children's fantasy novels "Harry Potter" by the British writer Joanne Catherine Rowling (pen name J.K. Rowling) is a course of Hogwarts School of Witchcraft and Wizardry, and one of the elective courses that Hogwarts began to study in the third grade. The teacher who teaches this course is Professor Victor. In the fourth and fifth grades, Harry Potter and Ron Weasley took divination classes, and Hermione Granger took arithmetic divination classes. Hermione likes this course very much. She said to Ron, "Compared with arithmetic divination, divination class is rubbish." Even in the O.W.Ls exam, the course was very difficult, but Hermione said after the exam that she thought it went well.

The so-called arithmetic divination refers to a kind of divination that uses numbers to explain clearly people's character and destiny or predict the future. Its other name is "Mathematical Secret". The present arithmetic divination is based on the Pythagorean philosophy and the Kabbalah tradition of Jewish mystical philosophy, which advocates that "the world is built on the power of numbers". Ancient Latin letters were set according to numerical values, so the sum of all letters was changed to 1 to 9 for divination. At present, the arithmetic divination is that the letters are divined in the order of ABC (when the letters J and S arrive, they will return the number 1) corresponding to the number 1 to 9.

Arithmetic divination is a fortune-telling method based on numbers and names, and it is also one of Hermione's favorite subjects at Hogwarts. This prediction of the future is not based on the interpretation of fuzzy images, like looking at a crystal ball, tea or palm in divination, or summarizing the inner meaning of things from random graphics or scribbled words. On the contrary, arithmetic divination is based on a series of rules and rigorous mathematical operations, and this kind of thinking happens to be Hermione's best and favorite job.

The word "arithmetic Mancy" comes from two ancient Greek words: "arithmo" (meaning "number") and "mancy" (meaning "wisdom"). For more than 2000 years, this fortune-telling method has been used by magicians and wizards to help people analyze their abilities and develop their wisdom. It can also help people overcome difficulties and point out the future development path. So this method is also called "mathematical numerology".
