How maths is applied in astrology and numerology?
The math used in astrology ranges from basic math of addition, subtraction, multiplying and dividing, plus trigonometry, using tables of logarithms, and calculations from ephemeris tables. Until recent times, astrologers had to do their own math work, but today many of them are using computer programs. The math used in numerology is completely different, as each letter of the alphabet represents a number from 1 to 9. Each letter in a person’s name is assigned a number, and the numbers are added together. The sum of these numbers is then added and in the process, the ending number remaining is said to represent a meaning according to that number.
