Without the parentheses, order of operations dictates that you do 9/.9 before you add the first 9, making the answer 19.<br /><br />Like Anon2:45, I also came up with (sqrt 9)!! / ((sqrt 9)! * (sqrt 9)!) = 3!! / (3! * 3!) = 720/36 = 20.<br /><br />I wonder if there are any other answers?Sethhttps://www.blogger.com/profile/11705017160747312919noreply@blogger.comtag:blogger.com,1999:blog-511467819948957047.post-50833151689342373082015-11-06T14:45:34.233-05:002015-11-06T14:45:34.233-05:00Nice answer though I still prefer (sqrt 9)!!/((sqr...Nice answer though I still prefer (sqrt 9)!!/((sqrt 9)! (sqrt 9)!).<br /><br /><br />Of course there's also (Arccos (-9/9))/9, but some consider trig functions inelegant in this sort of puzzle, and besides that gives 20° not the unitless 20 as requested.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-511467819948957047.post-61311617595227244902015-11-06T08:48:49.603-05:002015-11-06T08:48:49.603-05:00Nice job, we got this too!Nice job, we got this too!Joe Kupehttps://www.blogger.com/profile/07093091457723205068noreply@blogger.comtag:blogger.com,1999:blog-511467819948957047.post-5716485698744771182015-11-05T17:12:13.524-05:002015-11-05T17:12:13.524-05:00Too obvious for me.
