do9bvanc Posted October 27, 2007 Posted October 27, 2007 We can't use the number "7", so we count like this: 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, ... 65, 66, 68, 69, 80, 81, 82, 83, 84, ... What is the 2007th number? (And how can you count it out?)
uncool Posted October 27, 2007 Posted October 27, 2007 This is just asking "what is 2007 in base 9, with symbols 1,2,3,4,5,6,8,9,0?" Answer: [hide]2680[/hide] =Uncool-
supernova Posted November 5, 2007 Posted November 5, 2007 Isn't it 2230th , you divide 2007 by 9 and add the total to 2007. I guess
