Write mathematical formulas in Facebook Messenger

There are many features in Facebook Messenger that most of us are unfamiliar with. One such feature is to write mathematical formulas. This feature of Facebook Messenger is not new. But most people do not know this.
Facebook Messenger converts the equations written in Latex into mathematical equations. Latex is essentially a document preparation system. Most university level students are aware of this. Articles and scientific articles are usually produced in Latex which can be easily converted to PDF or another format.
When a formula is entered in Latex format in Facebook Manager, the manager automatically converts it to a mathematical formula.
As you type this into Messenger and enter it, the Messenger will change it according to the picture below.
This feature of Facebook Manager can be useful for college students.
