The use of LaTex Software has become the industry standard for the communication, and publication of scientific documents. It is an application that does not require any fees to be paid in order to use it, as it is entirely free.

However, you can use the LaTex Option in Word if you are a regular user of Microsoft Word and enjoy using various mathematical expressions and equations. If that's the case, this article will be helpful to you.

Since Latex Software provides many features for quickly typing complex mathematical equations, Microsoft recognizes Latex's ease of use, and MS Office, such as MS Word, began supporting Latex in Office 365 Version 1707 or later.

*Please keep in mind that if your thesis contains complex math equations, I recommend that you use Latex Software instead of Word. Word with Latex is appropriate for simple, usable math expressions and equations. This is my personal choice.*

### How to use Latex in Office 365 Version 1707 or Later?

Using Latex Syntax in Office 365 Version 1707 or Later is very simple. Here are the steps.

1 Open MS Word

2 Open the Latex Option by going to ** Insert** >

** Equations**

> **Latex**

or press the keyboard shortcut **+**

`ALT`

**=**

This will open a small Latex Equation Box.

3 Type your desired Mathematical equation inside that box in Latex Ways.

For example: `\frac{-b\pm\sqrt{b^2-4ac}}{2a}`

4 In that box, at the bottom right corner, click on the Down arrow and select "**Professional**"

5 Now, the above Latex will be processed into Equation Editors as shown below.

### How to convert back from Equation format to Latex Format in Word?

If you like to convert it back to Latex format you can easily do that. For this, again click on the down arrow and select **Linear **or simply press ** Ctrl** +

**+**

`Shift`

**.**

`=`

In this case, MS Word does not have an integrated Tex Processor; rather, it relies on pattern matching in order to transform straightforward LaTeX syntax into the format used by the system's native mathematical equations.

The formatting of the mathematical expressions and equations is merely an attempt to generate a Latex-style for MS Word.

The vast majority of the commonly used syntax in LaTeX is supported in the most recent version of Word.But even some of the Latex Keywords like **\Bar** , **\Middle**, ,**\Lbrack** , **\normal** ,**\|div** ,**\end **,** \dsmash** ,** \norm** etc are not supported properly.As may be seen in the following table, the Microsoft Official website provides a list of 20 different syntaxes that are not supported.

I really hope Microsoft will fix this issue in the near future.

**Conclusion**:

In this way, we can use Latex in MS Word.
