It is now four years since I first asked for support, and I would like to sincerely thank everyone who has helped me. BrainBashers doesn't show adverts, and I continue to depend on the ongoing support from everyone who enjoys the site.

Painter Pete, our local DIY expert, is renovating the local hospital.
He has to number each of the rooms in the hospital with plastic numbers.
However, he has run out of the number 9.
Unfortunately, he has no spare 6's available, which certainly would have been useful.
How many 9's must Pete buy in order to number all 1,000 rooms?
