# Maths & Operators Maths is used throughout scripting to get many different values, be it the distance between two objects or to calculate an equation.

## Maths & Operators

For example, a variable can be given data from an equation.

```variable = 5 + 1;
```

Although the above example is pretty pointless, as it adds one constant to another to make a constant, and you can just calculate it yourself and use the answer i.e.

```variable = 6;
```

But variables can be calculated using other variables, for example...

```varAnswer = var1 + var2;
```

varAnswer will be equal to the value of var1 plus the value of var2.

There are several operators that can be used in maths...

```+ :: Addition
- :: Subtraction
* :: Multiplication
/ :: Division
% :: Modulus
= :: Equals
```

There are also some more little-known operators such as...

```++ :: Increment (+1)
-- :: Decrement (-1)
+= :: Incrementation (requires number)
-= :: Decrementation (requires number)
```

Example of these in use...

``` var++; //Set var to var + 1
var--; //Set var to var - 1
var += int; //Set var to var + int
var -= int; //Set var to var - int
```
