Math Operations

You can do simple math using the math formatters, add, sub, muldiv and mod.

For example [[text:2:add 4]] returns a value of 6.
Or let's say the variable "counter" contains 6, here are some simple examples:

```[[var:counter:sub 1]] will return 5.
[[var:counter:mul 3]] will return 18.
[[var:counter:div 3]] will return 2.
[[var:counter:mod 4]] will return 2. The remainder of 6 divided by 4 is 2.```

IMPORTANT: You cannot directly use Decimal numbers for these operations.
For example you cannot use :
```[[var:counter:mul 3.5]]

But you can use [[var:counter:mul 3]]
```
To use Decimal / Floating point and execute more complex math operations, use JavaScript.

Multiple Operations: Pipe
Also, remember that you can string formatters together using the pipe "|" character (shift-backslash on American computer keyboards), such as
```
[[var:counter:add 1|mul 3]] calculates (6 + 1) x 3, or 21.
```
```

IMPORTANT: There are NO space around the pipe "|" symbol.
