Put a number in the box.  Put any number by the first dot.  Multiply the number in the box by the number by the dot.  Go to the next dot and multiply the new number by the number in the box, and so forth.  For example:  X2 with a starting number of 4.  You would multiply 2x4=8, then 8x2=16, then 16x2=32, etc.
