Shorts FIT Men's Knit Fly Football Dri NFL Nike Falcons 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 Nike Knit FIT Shorts Falcons Football Fly Men's Dri NFL and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andNFL Shorts Football Knit Men's Nike Dri FIT Falcons Fly 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 %}
