For plurals of multiple letters, we can again scrap the apostrophe and just add “s.” Example: “He is learning his ABCs right now.”

Is it 3s or 3’s?
Single-digit numbers are usually spelled out, but when they aren’t, you are just as likely to see 2s and 3s as 2’s and 3’s. With double digits and above, many (but not everyone) regard the apostrophe as superfluous. Most writers nowadays favor the 1900s, but some go with the 1900’s.
