Couloir Posted October 10, 2007 Share Posted October 10, 2007 6 7 8 9 = 24 You can add, subtract, multiply or divide any of the numbers ONCE. Ex: 2 3 4 5 = 24 is (5+4+3)2 = 24 Quote Link to comment Share on other sites More sharing options...

KaskadskyjKozak Posted October 10, 2007 Share Posted October 10, 2007 I had a teacher in jr. high who gave us this contest right after new year's day: using the numbers of the new year, exactly once and in order, and any math operators, find as many results as you can beginning with 0. Example: 2007 0 = 2*0*0*7 1 = 2^0 + (0*7) 2 = 2 + (0*0*7) 3 = 2 plustorial + (0*0*7) and so on. it gets hard quickly. some folks got up to a pretty high number (over a hundred) Quote Link to comment Share on other sites More sharing options...
