Katex not working

[CyberDu]

Hi,
I am trying gitbook, I have the free version and still on trial.
I am trying to use Katex and try some math formulas but the inline formulas don't work. I tried for example $V_j=x^2$ and it doesn't work.
Can someone tell me what am I doing wrong?
Thanks

Hey @CyberDu! Are you sure you are using the correct format? I tested it, and it's working for me!
