**Concepts**

The absolute difference between two numbers is the difference between their magnitudes, without regard to their signs. It is a measure of the distance between two numbers on a number line.

The absolute difference between two numbers can be calculated using the following formula:

```
|a - b|
```

where `a`

and `b`

are any two numbers.

For example, the absolute difference between 5 and 3 is 2, because |5 – 3| = 2. The absolute difference between -5 and 3 is also 8, because |-5 – 3| = 8.

**Formula**

The formula for calculating the absolute difference between two numbers is as follows:

```
|a - b|
```

where `a`

and `b`

are any two numbers.

**Interesting facts**

Here are some interesting facts about absolute difference:

- The absolute difference between two numbers is always greater than or equal to zero.
- The absolute difference between two numbers is equal to zero if and only if the two numbers are equal.
- The absolute difference between two numbers is equal to the distance between the two numbers on a number line.
