The Principle of Name Numerology
The Pythagorean system assigns each letter of the alphabet a numerical value from 1 to 9 in sequence. This allows any name to be converted into a sequence of values that, when summed and reduced, produce a unique number.
The full birth name generates three distinct numbers based on which letters are included in the calculation:
| Number | Letters used | Description | |--------|-------------|-------------| | Expression | All letters | Communication profile and abilities | | Soul Urge | Vowels only | Internal motivations | | Personality | Consonants only | External impression |
The Pythagorean Assignment Table
| Value | Letters | |-------|---------| | 1 | A, J, S | | 2 | B, K, T | | 3 | C, L, U | | 4 | D, M, V | | 5 | E, N, W | | 6 | F, O, X | | 7 | G, P, Y | | 8 | H, Q, Z | | 9 | I, R |
Note: Y is treated as a consonant (value 7) in the standard Pythagorean system.
Expression Number: All Letters
The Expression Number is obtained by summing the values of all letters in the full name and reducing the result.
Describes: how a person communicates, their natural abilities, and the impression they generate in professional and social environments.
Example with the name "ANNA TORRES":
A-N-N-A T-O-R-R-E-S
| Letter | Value | |--------|-------| | A | 1 | | N | 5 | | N | 5 | | A | 1 | | T | 2 | | O | 6 | | R | 9 | | R | 9 | | E | 5 | | S | 1 |
Sum: 1+5+5+1+2+6+9+9+5+1 = 44 Reduction: 4+4 = 8
Expression: 8
Soul Urge: Vowels Only
The Soul Urge is obtained by summing only the values of the vowels in the full name.
Describes: internal motivations, what a person seeks privately, and the emotional needs that guide their decisions when there are no external pressures.
Example with "ANNA TORRES":
Vowels in the name: A, A, O, E (N, N, T, R, R, S are consonants)
| Vowel | Value | |-------|-------| | A | 1 | | A | 1 | | O | 6 | | E | 5 |
Sum: 1+1+6+5 = 13 Reduction: 1+3 = 4
Soul Urge: 4
Personality Number: Consonants Only
The Personality Number is obtained by summing only the values of the consonants in the full name.
Describes: the initial impression a person projects before being known in depth. It is the external interface of the profile.
Example with "ANNA TORRES":
Consonants in the name: N, N, T, R, R, S
| Consonant | Value | |-----------|-------| | N | 5 | | N | 5 | | T | 2 | | R | 9 | | R | 9 | | S | 1 |
Sum: 5+5+2+9+9+1 = 31 Reduction: 3+1 = 4
Personality: 4
Verification: The Relationship Between the Three Numbers
The three name numbers are mathematically related:
Expression total = Soul Urge sub-total + Personality sub-total (before final reduction)
Using the "ANNA TORRES" example:
- Vowels: 1+1+6+5 = 13
- Consonants: 5+5+2+9+9+1 = 31
- Total: 13+31 = 44 → 4+4 = 8 ✓ (matches the Expression)
This relationship allows you to verify the calculation: if the sum of the sub-totals doesn't match the total sum of all letters, there is an error in the vowel-consonant separation.
Which Name to Use
The Pythagorean system uses the full name from the birth certificate as input data:
- All first names (not just the first)
- All surnames
- No abbreviations
- No nicknames or stage names
Middle names and compound surnames are always included. The birth certificate is the authoritative reference.
Calculate Your Name Numbers
The Name Analysis calculator applies the Pythagorean table automatically, separates vowels and consonants, and displays all three results (Expression, Soul Urge, Personality) with a letter-by-letter breakdown. No manual calculation required.
