Yes, and the site guidelines ask submitters to drop magic numbers from titles:

If the title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."

... although I notice that it's worded more restrictively than I remember. It should cover magic numbers in general, not just at beginnings. (Edit: fixed now!)
