@HumphreyYang this typo should be incorporated in the new PR

Many thanks @mmcky. I have added this into the branch.

I am still getting this error:

! Paragraph ended before \split was complete.

                   \par

But we did not use split in this lecture. Could you please let me know where to pin down this error?
