The reason is that models derived directly from the n -gram frequency counts have severe problems when confronted with any n -grams that have not explicitly been seen before – the zero-frequency problem .
An example of multiplying binomials is (2x+1)×(x+2) and the first step the student would take is set up two positive x tiles and one positive unit tile to represent the length of a rectangle and then one would take one positive x tile and two positive unit tiles to represent the width. These two lines of tiles would create a space that looks ...
