Frequently Asked Questions
What is an expression number in numerology?
The expression number, also called the destiny number, is one of the core numbers in numerology derived from the full birth name as it appears on your birth certificate. Each letter of the alphabet is assigned a numerical value using the Pythagorean system where A equals one through I equals nine, then J restarts at one through R equals nine, and S restarts at one through Z equals eight. All letter values are summed and reduced to a single digit or master number. This number reveals your natural talents, abilities, shortcomings, and the overall direction of your life path according to numerological tradition.
How is the expression number different from the life path number?
The life path number is calculated from your date of birth and represents the journey and lessons you will encounter throughout your life. The expression number is calculated from your full birth name and reveals your inherent talents, abilities, and personal characteristics that you carry with you. Think of the life path number as the road you are traveling on, while the expression number represents the vehicle you are driving along that road. Both numbers work together in a numerology chart to give a fuller picture of your personality and purpose in this lifetime.
