I am fairly sure that almost everyone with a cs degree can calculate something like 56 * 13 with a pen, paper and some time. The thing is that you can teach almost anyone to memorize a table which is why you can teach them to multiply single digits. But once you try to teach them how to follow an algorithm a lot of people just wont get it, which is why multiplying things they haven't memorized gets almost impossible for some.
