silly specific: the minus sign is a separate character. The dash equivalent is the en dash (–), versus the larger em (—) and smaller hyphen (-).

The en dash is also used in things like scores (3–2 Turkey), votes (the bill passed 58–42), or connecting words where the second part is longer than one word (the Australia–New Zealand alliance.) You can remember the latter as, "a hyphen isn't big and strong enough to hold on to more than one word.

If you're on a mac, pressing Option+- is the en dash and Option+Shift+- is the em dash.
