What is Latex?
Latex is a mathematical composition program that is standard for most professional math writers.
It bases on the TEX composition program created by Donald Knuth at Stanford University (the first version that appeared in 1978).
Leslie Lamport was responsible for creating LATEX, a more user-friendly version of TEX. The LATEX programming team has made the current version of LATEX 2ε.
It can be written in two ways: textual and mathematical; text mode is for text; write like in any text editor.
All math data is in math mode. The dollar sign ($) is to toggle between the two methods.
LaTeX: What is the command for the plus-minus sign?
- It is already very late, but for others like me who are also looking for this answer:
- Indeed, everyone will answer correctly. It would be best if you used \ pm. But the package for this command is \ Siunitx.
- Also, to display 20 ± 18, you need to write $ 20 \ pm $ 18. Unsigned $ lines can overlap.
- I have been using LaTeX for ten years as a student and graduate student in mathematics.
- The usual plus or minus character is \ pm.
- If you want it to be with a minus at the top, i.e., minus plus is \ mp.
- The plus or minus sign is represented by LATEX as \ pm; it looks like this: ±.
- On the other hand, the minus plus sign is marked as \ mp; it looks like this: ∓.
- For example, the standard formula for factorizing the sums and differences of cubes would be x ^ 3 \ pm y ^ 3 = (x \ pm y) (x ^ 2 \ mp XY + y ^ 2) or x3 ± y3 = (x ± y) (x2∓xy + y2).
Uses of LaTeX
- Latex is far from dead, and it is the primary Word processing tool in academia. I don’t know of any company that uses Latex.
- It is the predominant format requested by scientific journals because they can immediately use the latex input document without further processing from Word to Latex.
- I prefer Latex for any text longer than a few pages; I would not use Latex for writing letters or more, for example.
- Latex allows me to write more efficiently than Word because it saves me from using my mouse to format the text.
- “keyboard sensitivity” is related to the fact that I am also a software developer, so I am used to thinking in code, and therefore code, rather than using a mouse.
- Also, I am creating a relatively large document class that provides the functionality I need to create documents formatted according to our formatting standards.
- I prefer Latex because it provides the best result in terms of the fonts provided and document formatting.
- Secondly, for me, Latex is the weapon of choice for creating standardized documents from data and blocks of text from databases.
How to enter a plus/minus sign ±?
- The more or less usual character is \ pm. If you want a minus on top, i.e., minus-plus, it’s \ mp.
- While holding down the ALT key, enter 0177 on your keyboard.
- On Mac OS:
- Hold down the Shift and Option keys and press =
- In HTML:
- ± or & # 177;
What does the plus sign above the minus sign mean?
- (Mathematics) ± symbol plus or minus, used to indicate approximation accuracy (Example, “Result is 10 ± 0.3”, which means that the result is anywhere in the inclusive range of 9.7 to 10.3 ).
- It is a convenient shorthand for a quantity with two possible values of the opposite sign and the same amount.
Is Latex dead? If so, what are the current alternatives?
- It is entirely possible with Python scripts accessing the database and publishing latex code that is processed on the server that I run when I generate PDF documents.
- I could have done the same with Word, but I had to use commercial products that we cannot afford as a research institute.
- However, Latex has a few annoying flaws: Word is much more robust in collaboration and multi-author document review.
- Also, writing VBA macros is a cool feature, especially when passing data from a Word document to my database (I use this feature to create traceable requirements in specs).
