##### LaTeX to XML Math Delimiters - 35 entries

Vim is amazing when used to edit MediaWiki text, but typing "<math> . . . </math>" can be tiresome and frustrating if formulas are used often. LaTeX delimiters are so concise and even come in two flavors: "\( . . . \)" for inline math and "\[ . . . \]" for centered formulas. The goal is to perform the following conversions: "\( . . . \)" becomes "<math>. . .</math>" "\[ . . . \]" becomes "<center><math>. . .</math></center>"

##### Chinese Multiplication Table - 50 entries

Print a Chinese multiplication table in Vim. In China, every kid is asked to memorize this table. And thanks to the mono-syllabism of Chinese characters, it is not that hard. Printing the multiplication table is also a good exercise for programming beginners. For-loop, escaped characters, etc... There should be some special ways to print it in Vim.
