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