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.
These clues are sometimes the only way you can start a puzzle, so these combinations are worth remembering.
The numbers shown in green are those where there is only one combination. For example there is only one way to make 17 with two digits: 8 + 9.
