rookie1ja 13 Posted March 30, 2007 Report Share Posted March 30, 2007 1996 - Back to the Number Puzzles Using the numerals 1, 9, 9 and 6, mathematical symbols +, -, x, :, root and brackets create the following numbers: 29, 32, 35, 38, 70, 73, 76, 77, 100 and 1000. All the numerals must be used in the given order (each just once) and without turning upside down. This old topic is locked since it was answered many times. You can check solution in the Spoiler below. Pls visit New Puzzles section to see always fresh brain teasers. 1996 - solution I used [brackets] as the symbol for root.

Guest Posted July 13, 2007 Report Share Posted July 13, 2007 I get all of them except the answer 29... please explain. It would end up being -1+3 + (3^6) which is 2 + 729 = 731 The only way it would work if is 2 is added to 27. To get 27 the multiples are 3x3x3 and I can't figure that out with 9 and 6.

You forgot a root: -1 + root(9) + root[root(9)^6] =-1 + 3 + root[3^6] =-1 + 3 + 3^3 =-1 + 3 + 27 =29 Link to post Share on other sites

Guest Posted March 22, 2008 Report Share Posted March 22, 2008 1996 - Back to the Number Puzzles Using the numerals 1, 9, 9 and 6, mathematical symbols +, -, x, :, root and brackets create the following numbers: 29, 32, 35, 38, 70, 73, 76, 77, 100 and 1000. All the numerals must be used in the given order (each just once) and without turning upside down. For 32 there is another way to do it: -1+[9]x9+6=32 For 38: 19/[9]/6=19x6/[9]=38, actualy is the same,just 1 step before the shown equation. Link to post Share on other sites

Guest Posted March 4, 2009 Report Share Posted March 4, 2009 another solution for 76: 91 - (9+6) = 76 91 - 15 and for 35: [[9]6] + 9 - 1 = 35 [3^6] + 9 - 1 3^3 + 9 - 1 27 + 9 - 1 = 35 numbers need to be in 1996 order.... Link to post Share on other sites
