I don't know what it is either. My advice is to use the old multiplication tables. I assume you've memorized these.
I always thought that mountain multiplication resulted in large families. Be fruitful, and multiply.
Mountain multiplication Google it. It is music to help with memorization of the tables. Look for it on CD Baby.
