I want to upload a pdf file while answering a question, but could find no such option on both the desktop and mobile version.

Is this present and I'm missing it, or absent?

    $\begingroup$ What's in this pdf that's so essential to the answer but which you can't put in the body of the post itself? $\endgroup$ – Emilio Pisanty Apr 2 '17 at 2:03

Stack Exchange does not support vector-type images (SVG, pdf, etc.). This means that you can't upload pdf files here. What you can do is to take a screenshot of the file - or to use any vector-to-raster converter - and upload the picture. But please bear in mind that if the content of the pdf is text and equations, you are supposed to actually type those, not to include a picture of the text. Only use pictures to include actual graphs, such as diagrams, photos, drawings, etc.

In case you don't know how to type math equations here, see MathJax basic tutorial and quick reference. For more information about vector-type images, see Allow SVG image uploads.
