# Bridge numbers calculator

Bridge numbers measure the gap between two core numbers in your chart. Numerology reads each as the quality that brings the two together.

## How the bridges are calculated

Reduce each core number to one digit first (11 counts as 2, 22 as 4, 33 as 6), then take the difference:

- **Life Path to Expression bridge**: the difference between your [Life Path](/life-path-number-calculator) and your [Expression](/expression-number-calculator).
- **Soul Urge to Personality bridge**: the difference between your [Soul Urge](/soul-urge-number-calculator) and your [Personality](/personality-number-calculator).

Each bridge is a number from 0 to 8. A bridge of 0 means the two numbers already agree.

## What the bridges describe

The Life Path to Expression bridge connects the road you are on with the talents you bring to it. The Soul Urge to Personality bridge connects what you want inside with how you come across. Numerology reads each bridge number as the quality to develop to close the gap: 1 confidence, 2 cooperation, 3 expression, 4 discipline, 5 adaptability, 6 responsibility, 7 reflection, 8 balance between the material and the personal.

## Frequently asked questions

### What does a bridge of 0 mean?

That the two numbers share a root, so there is no gap to bridge between them.

### Why are master numbers reduced?

A bridge is a difference, and differences are only meaningful between single digits, so 11, 22 and 33 count as 2, 4 and 6.
