# Arithmetic and Unary Operators

Introduction: Hello, this page will teach you about another two types of Operators in Java, Arithmetic and Unary. Arithmetic Operators - What are they? Arithmetic Operators are symbols used to perform a mathematical sum. There are five types of these:
 + Add - Subtract / Division * Multiplication % Modular/Remainder
All of these operators have clear uses for anyone with basic knowledge of Math. Unary Operators - What are they? Unary Operators are used to manipulate a number value - at least, that's what I say. Again, there are five types of Unary Operators:
 + Indicates Positive Value - Negates An Expression ++ Increments Value by 1 -- Decrements Value by 1 ! Inverts Boolean Value
Examples: Here is an example of how Arithmetic Operators are used:
`int tutorial = 2;System.out.println(tutorial);tutorial = tutorial + 1;System.out.println(tutorial);tutorial = tutorial - 2;System.out.println(tutorial);tutorial = tutorial * 50;System.out.println(tutorial);tutorial = tutorial / 3;System.out.println(tutorial);tutorial = tutorial % 10;System.out.println(tutorial);`
which gives the output:
```2
3
1
50
16
6```
And here is an example of how to use Unary Operators:
`int tut = 2;System.out.println(tut);tut++;System.out.println(tut);tut--;boolean opposite = false;if (!opposite){	System.out.println(tut);}`
Which gives the output:
```2
3
2```
