Maybe this question belongs to some other place such as Academia SE, but I am interested in the specific case of the field of mathematics, so please forgive me.

I am writing my first research presentation in mathematics, and I will use a slide format such as Powerpoint or Google Slides. Right now I was trying to make use of some add-ons on Google Slides, and it works okay, and looking okay at least to me. But when I see some other mathematician's presentation, I can clearly see that they did not use TeX add-ons and share some standard style. So my questions are:

- Is there any common method or tool or software to write a presentation (specifically, slides) in mathematics?
- If there is, will it be recommended to follow "the standard"? Or people will not care if it is out of standard shape?

Thank you in advance.
