If your PDF contains formulas or equations, whether they are created using text or inserted as images and screenshots, they need to be tagged in Formula tags. The Formula tags, then, need to have Alt text.
In CommonLook PDF, you'll find the button to create (or convert to) Formula tags in the ribbon, in the "Other tags" group, in the the dropdown menu for "Standard tags."
Important Note: You can’t just put the formula in the Alt text for the screenshot, you have to actually write it out. This not only includes writing out symbols like “Function,” “Sigma,” and “Square root,” but also more simple things like “inches” instead of using quotation marks. This is to ensure not only that the symbols get read correctly but also because, if you’re using quotation marks to indicate inches, for example, the screen reader may not read that punctuation.
Follow this link for more information about Alt text in CommonLook PDF.
The same is true for Chemical equations, Music, etc.
