### Options

Counter allows you to perform such math operations: addition, substraction, multiplication, division and modulo (reminder of a devision). Number can be represented as a static or a subcounter value.

{% hint style="info" %}
You'll need to configure separate subcounter if you want to use counter value - it's not possible to use value of already existing counter, however you can just select the same options.
{% endhint %}
