Using an apostrophe to form a plural noun

Hi,

I have a question regarding the use of apostrophes to form plural nouns like this:

... with A's and B's moving farther down ...

Why not "As" and "Bs" to make them plural? Can you kindly give me some other examples of this kind?

I think the best way to form plurals of this kind is just to add an "s", without the apostrophy.

With single letters, don't use the the apostrophe. You use them with an abberviation or acronym to show that the "s" is there to make it plural is not part of the original abbrevation/acronum.

Let's say you work with two things, one known at PBCS and the other as PBC. If you wanted to make PBC plural and wrote it as PBCs, your reader could be confused - but if you say PBC's, it's clear. O
