I'll just continue to disagree, I guess. I was able to learn algebra just fine even though I didn't know my multiplication tables, while the rest of the class spent a year memorizing them. Our methods of deciding when someone "knows" something so they can "pass" needs to be radically rethought. We spend all our time practicing how to integrate by parts when in reality a computer will do that for you, and youre needed for higher level thinking and abstractions that the math classes don't bother to get to until graduate school. Sad imo.
