I heard of some study once which looked at what the poorest and best
students had learned in a math class. It turned out that the worst
students had actually learned *more* concepts. For instance, they
learned the equation for the area of a square, the area of a rectangle,
the area of a right triangle, etc. The best students, however, only
learned a few concepts, like "area" which they could than apply to solve
many different problems.
I wonder if what's going on here is something like that where people
have learned the concept of "multiply small numbers" without ever really
grasping the meaning of "multiply" in general (or many even "number" in
general).
