XY-pic works with most of the many formats available. One can write mathematical notation with blocklatex convention or blocktex convention both does the same thing practically but the first way is latex convention way to represent mathematics in LaTeX document while the later is supported by TeX while latex being built on the top of TeX processor latex supports both the implementation of displaying math. Simply click on the x-symbol at the end of the input to open the LaTeX editor or click on an existing expression.
So Lets see the latex code of Set Notations one by one.
