Hi. I note you've been working on something about subtraction without borrowing, and that you mentioned (last month! Sorry about the delay!) that you were having trouble with the syntax of Wiki-markup. Since you've been editing the article since then, I've concluded that you've resolved your problems; if you still have difficulty, check here for help.

Could I ask, though... have you read our policies on original research? You described this as a new method, and I'm a little concerned. DS (talk) 15:02, 24 January 2011 (UTC)

Frankly, I cannot judge this material. My degree is in chemistry, not mathematics. I strongly suggest that you discuss the issue with the people on the Mathematics project. DS (talk) 12:40, 27 January 2011 (UTC)
