# Inserting mathematical expressions

Hello,

I have just successfully installed TAO 3.3 on an apache server, and the first problem I face is the inclusion of mathematical expressions.

I followed the instructions in the guide: https://userguide.taotesting.com/3.3/items/math-expressions, but it doesn't work for me:

- the custom interaction that I see in my installation is "Math entry" and not "LaTeX",

- in the text field under the mathematical symbols ... I can't insert any text.

I also tried to follow the procedure indicated in the guide https://hub.taotesting.com/articles/third-party-tools-and-libraries/enable-math-expression-in-items, downloading the reduced Mathjax archive and transferring the file in the indicated folder (at this URL http://docs.mathjax.org/en/latest/installation.html#obtaining-mathjax-via-an-archive there is nothing).

Surely I didn't understand and something is wrong. Can you help me?

Thanks

## Comments

I add that the Pi symbol, which should appear as shown here https://forum.taotesting.com/discussion/comment/226/#Comment_226, is not there.

Here are the instructions for install MathJax for TAO which can be found in the Admin Guide -

sudo wget https://hub.taotesting.com/resources/taohub-articles/articles/third-party/MathJax_Install_TAO_3x.sh

sudo chmod u+x MathJax_Install_TAO_3x.sh

sudo ./MathJax_Install_TAO_3x.sh

Thanks also for this help!

My pleasure
