**Concepts**

An integer is any number that can be represented without a fractional component. Integers can be positive, negative, or zero.

Adding and subtracting integers are two of the most basic arithmetic operations. Adding integers is the process of combining two or more integers to find their sum. Subtracting integers is the process of finding the difference between two integers.

**Formulae**

The following formulae are used to add and subtract integers:

```
Addition: Integer 1 + Integer 2 = Sum
Subtraction: Integer 1 - Integer 2 = Difference
```

Where:

- Integer 1 is the first integer
- Integer 2 is the second integer
- Sum is the sum of Integer 1 and Integer 2
- Difference is the difference between Integer 1 and Integer 2
