"rule of product or multiplication principle is a basic counting principle (a.k.a. the fundamental principle of counting)."(WpEn:Rule_of_product)
rule of product = multiplication principle is_a basic counting_principle
rule_of_product(=product_rule) = multiplication_principle : counting_principle { counting principle Up: counting 원리,principle }
=,rule_of_product =,product_rule =,multiplication_principle .



이건 product_rule 의 다른 뜻. product_rule =,product_rule . product_rule
