Hey there. What is the Latex code for cancellations?. Suppose we posted a
multiplication or what not and wanted to show the strikethroughs that show
cancellations, what is the best way. I used to use \sout but that does not
work. I know there is a diagonal one and a horizontal one. I like the diagonal
because it shows up best. I can not remember what it is and can not
find it anywhere.
