Hello, welcome to Wikibooks!

Thanks for your edits to the Mental Math book. I thought it might be time to say hello.

Also, I was wondering if for your subtraction section in 'mental' math, if it would be cleaner to always subtract from 9 and then add 1 at the end. So, 1000 - 258 = 1 + 999 - 258 = 1 + 741 = 742. We wouldn't have to present it algebraically, of course. Just say 'add 1 at the end'

Oh, and below are the standard tips we give to all new users. Welcome again! -- Kowey 12:50, 13 July 2007 (UTC)
