But it's not correct. <br /><br />In fact 0.999... and 1 are simply two ways to express the same number. Here's one proof (there are many):<br /><br /><b>n = 0.999...</b><br />10n = 9.999...<br />10n - n = 9.999... - 0.999...<br />9n = 9<br /><b>n = 1</b><br /><br />QED (or in vf: CQFD)Páraic Maguirehttps://www.blogger.com/profile/08060907238979040187noreply@blogger.comtag:blogger.com,1999:blog-34516254.post-52500671835620360352013-11-01T01:40:14.940+01:002013-11-01T01:40:14.940+01:00I can't see how 0,999 ad nauseam could equal 1...I can't see how 0,999 ad nauseam could equal 1. It would be infinitely close, but not equal. Equal means there's no difference whatsoever, which is false in that case.<br /><br />At least, that's my take on it, even though admittedly my maths are getting rusty...Nicolas D.noreply@blogger.com
