Also known as your destiny number, an expression number is said to delve into your abilities, desires and personal goals. It could also make you aware of any inherent traits that you may carry.
Your expression number is calculated by converting your FULL birth name (including any middle names) into numbers using the Pythagorean chart. This type of chart correlates a letter with a single digit number. Then, the total sum is broken down to a single digit number. Once again the master numbers apply to your destiny number and are not reduced any further.
Whatever expression number you are left with has a different meaning and works in combination with other core numbers to build a picture of who you are and what you’re about as a person in the wider universe.
