The Apostrophe with Numbers, Letters, and Abbreviations
Rule: The plurals for capital letters and numbers used as nouns are not formed with apostrophes.
Example: She consulted with three M.D.s.
Example: She went to three M.D.sí offices.
The apostrophe is needed here to show plural possessive.
Example: She learned her ABCs.
Example: the 1990s
Example: the í90s or the mid-í70s
the í90ís or the mid-í70ís
Example: She learned her times tables for 6s and 7s.
Exception: Use apostrophes with capital letters and numbers when the meaning would be unclear otherwise.
Example: Please dot your Iís.
You donít mean Is.
Example: Ted couldnít distinguish between her 6ís and 0ís. You donít mean Os.
