Underline and Strikethrough
Underlining a text is possible with the simple \underline command in LaTeX, but like the case changing commands, it comes with its problems. A long piece of text in the scope of \underline command will not break properly to the next line. To solve this problem, we can use the ulem package . This package mainly changes the way \emph command works: instead of using italics, it emphasizes the text with underlining it. We can set it to not break the regular working scheme of \emph command by adding it with normalem option. This package introduces \uline command for making a text underlined. It also comes with six more different ways to differentiate a piece of text with strikes and lines: \uuline double-underlines a text, \uwave underlines a text with a wavy line, \sout creates a strikethrough text, \xout strikes the text with hatching, \dashuline underlines a text with a dashed line and \dotuline underlines a text with a dotted line. Below, the effects of these commands are shown.

\uline{Underlined}
\uuline{Double-Underlined}
\uwave{Wavy-Underlined}
\sout{Strikethrough}
\xout{Struck with Hatching}
\dashuline{Dashed Underline}
\dotuline{Dotted Underline}
\end{document}

Old Style Numbers
The default LaTeX font Computer Modern, and many other fonts come with two sets of numeral characters, the regular numbers and old style numbers. These old style numerals have different heights and depths from the standard ones. They are also known as medieval or lowercase figures. We can print these numbers by using \oldstylenums command. In the next example, we print two sets of numbers together.
...
1234567890
\oldstylenums{1234567890}
...
