How to write a Math formula on Facebook Messenger

Facebook Messenger is the drafting of the basic mathematical formula, like software LaTex ( Reference : Texmaker - Software LaTeX editor ) Math enthusiast.

However, Facebook users  can only edit mathematical equations on the desktop version of Facebook Messenger, but with the mobile version, maybe we will need to wait a little longer.

How to write Math formulas on Facebook Messenger

In fact, entering math formulas on Facebook Messenger is not a new feature. But for some reason, it was forgotten for quite a long time and not paid enough attention. 

Only now, when the back-to-school season is going on and LaTex is being used a lot in STEM courses, this Facebook Messenger trick will be "excavated" and hopefully will help Facebook users in the process. study, especially when doing group exercises.

To be able to write Math formulas on Facebook Messenger , we need to understand the following basic requirements:

• Rules for drafting Mathematics in LaTeX.
• Rules when writing LaTeX formulas in Facebook Messenger.

For example, as in the table below, we can see the typing rules of some specific mathematical symbols and formulas such as: 

• Vector ( ) = \ vector {abc} 
• = \ left (a \ + \ frac {b} {b} \ right) 
• ...

But when we want to express it as a specific formula on the free Facebook Messenger chat tool, we need to add "$$" to the beginning and end of the formula, specifically: 

\ vec {abc} to $$ \ vec {abc} $$

\ left (a \ + \ frac {b} {b} \ right) to $$ \ left (a \ + \ frac {b} {b} \ right) $$

However, with some special Math formulas or symbols, we will not be able to use them as usual, but need to type according to the convention table as below.

For many people, remembering this rule is much more difficult and complicated than solving Math problems , but we also have a very useful support tool, hotsmath or codecogs, that can help remember these rules.
