Maybe *some* kids need to have their math facts down before attempting multi-digit multiplication, but not all kids. DS would have gone nuts if we had withheld showing him long multiplication and division until he had mastery of his times tables. In fact, practicing long multiplication problems turned out to be a great way to practice his math facts.
