Question

why is an apostrophe used in pluralization here:Ted couldn't distinguish between his 6's and 0's.

Accepted Answer

You need to use the apostrophe to indicate the plural of zero or it will look like the word Os. To be consistent within a sentence, you would also use the apostrophe to indicate the plural of 6's.
