How can I strike through an expression (e.g. "2x") obliquely, e.g. from bottom left to top right, so as to indicate cancellation? With the
\sout command from the
ulem package, I can only strike horizontally.
If you're not satisfied with how the cancellation starts below the 1 and ends above the 0, have a look at Diagonal strikeout starting too low and ending too high.
