It determines how operators are grouped when different operators appear in a single expression. For example, * has higher precedence than +. So, if we have a + b * c ;it means multiply b and c and then add a to the result. Precedence of operators can be overridden by using parentheses.
This is table of AWK's operator precedence order from highest to lowest:
