Red Sweater Men’s Red Dark Stripe Stripe Sweater Men’s Dark Men’s 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 Dark Men’s Red Men’s Stripe Stripe Sweater Men’s Dark Sweater Red and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andRed Stripe Dark Stripe Sweater Red Men’s Men’s Men’s Sweater Dark 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 %}
