This tutorial will help you writing your answers using LaTeX format. What is LaTeX? Well with short words I should describe it like that - LaTeX is a document preparation system for high-quality typesetting. It is most often used for medium-to-large technical or scientific documents but it can be used for almost any form of publishing.
What if we need to type some math formulas or special symbols? We are not able to do that using the normal input way. That’s where the LaTeX can help us.
As you can see in the Math section in the forum I have already used the LaTeX implementation, so you can look around and see how it is going to look after the word processing. I will give you another example here, so you can be sure what I am talking about.
\begin{equation}
Pyramid_n = \sum_{i=1}^{n} \frac {i(i+1)} {2} \\
Pyramid_n = \sum_{i=1}^{n} \frac {i^2} {2} +\sum_{i=1}^n\frac {i} {2}\\
\end{equation}
It is really comfortable and user-friendly to use LaTeX format. I advise you to see the next chapter with the instructions how to use it.
I have tried to collect the most common commands used in math formulas too.
LaTeX is useful not only here in the forum, but all the largest math communities.
So I strongly advise you to take a look and understand the basic concepts.
