The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc.

For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)
