Accessable Mathematical formulas

Hello all,

As a digital accessibility consultant, I was asked to advise on
mathematical formulas written in latex and uploaded to a website as a PDF
file. I would like to know what is the best way to write mathematical
formulas that are also accessible to screen readers and assistive
technologies, on a website, today?

Thanks in Advance.
