Apostrophes: do you know the only rule?

I helped a friend recently who was editing some training materials. He got stuck on when to use an apostrophe in the following examples. Which of these needs one and where?

Type 1s are the creative thinkers in the team
In threes attempt the first exercise

That’s right – neither needs an apostrophe. 1s and threes are simply plurals. So no apostrophe is needed. Perhaps this is a little tricky, because of the question of whether to write out numerals or not, but I can’t help thinking that dealing with apostrophes is really very simple. In fact, it all comes down to just one rule.
