Even though this article was quite difficult to read and I could hardly understand many of the words that were used in the article I will try to make my best effort to answer the question.  The reason that I believe that Shulman is trying to deconstruct math is because she believes that it is different for many people.  She feels that math is not the same through out the whole world.  I believe on the contrary that math is the same throughout the whole world.  Math has many of being done, but you come out with the exact same answer at the end or else it is wrong.
         I think that math should not be deconstructed because math and science are two of the subjects that are the same around the whole world.  When Shulman says that she wants to deconstruct math, I think that is because she feels that it is not the same throughout the world.  I was once told that math is a universal language and I still believe that today.  No matter where you are or what language you speak what color you are, or how fat or skinny you are, math is all the same.  Two plus two will always equal four, and science will also be the same.
         Shulman says that she thinks that math is culture.  She explains through a couple of word problems why she believes that culture and language influence mathematics, and that different societies have different versions of mathematics.  And the reason that I think she wants to deconstruct mathematics is because she associates mathematics with culture, culture with men, and nature with female.  So therefore she does not want mathematics to be constructed she wants it to be deconstructed so that men and women would be equal.
