Twig allows you to calculate with values. This is rarely useful in templates
but exists for completeness' sake. The following operators are supported:
* `+`: Adds two objects together. Usually the objects are numbers but if both
are strings or lists you can concatenate them this way. This however is not
the preferred way to concatenate strings! For string concatenation have a
look at the `~` operator. `{{ 1 + 1 }}` is `2`.
* `+`: Adds two objects together (the operands are casted to numbers). `{{ 1
+ 1 }}` is `2`.
* `-`: Substract the second number from the first one. `{{ 3 - 2 }}` is `1`.
