Advanced Advanced Advanced Advanced Trackpant Classics Trackpant Classics Classics Trackpant Classics Order of operations

In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

{% if true or false Advanced Advanced Advanced Classics Classics Classics Trackpant Trackpant Trackpant Classics Advanced and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andAdvanced Classics Advanced Trackpant Advanced Advanced Classics Classics Trackpant Trackpant Classics false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
  false
{% endif %}
