LaTeX: Insert underscore - how to do it

Both for mathematical formulas and for various text projects, you need to know how to insert an underscore. As for many other aspects, you need to use a command here as well, because LaTeX has stored the underscore as a special character in its internal programming.

How to insert an underscore

In LaTeX you have the possibility to insert an underscore in a mathematical environment, to underline a letter or even a whole word.

1. In order to insert an underscore in text mode, you have to select the backlash. After that, write the formula /_. Thereupon LaTeX will put an underscore in its place.
2. Also within a mathematical formula you should proceed as described above.
3. If you want to underline a whole word, you have to proceed differently.
4. In LaTeX, enter the command /underline(text). Replace the term "text" with the appropriate word.
5. So you can also proceed if you want to represent a whole sentence or section underlined. It is important that you do not use a space and the brackets thus completely enclose the text.

Preparation is everything

The presentation in LaTeX is much more appealing than with other word processing programs. However, you will also have to put in more work to achieve this. Therefore, you should start by creating a table for yourself from which you can take all the essential commands to make the work more efficient.
