That's how many days God took to create it.

7 is actually a lucky number in the US. I can;t find any definitive answers as to why 7 is a LUCKY number, but here is what I did find.\n\nWhy is seven lucky? We are not entirely certain - but we did find many special sevens : from the Seven Wonders of the Ancient World ... to seven days of the week. \n\nSeven more sevens: \n• Pythagoreans called it the perfect number, 3 and 4, the triangle and the square, the perfect figures.\n\n• Seven ancient planets - the sun was the greatest planet of the ancient seven and next to the sun, the moon, changing in all its splendour every seventh day. Seven visible planets and luminaries (Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn).\n\n• Books ...The Seven Pillars of Wisdom by T E Lawrence, Enid Blyton's Secret Seven series ... Stephen Covey's Seven Habits of Highly Effective People ... Reiki and the Seven Chakras ...\n\n• Seven Deadly Sins.\n\n• The Trumpton fire brigade. (Pugh, Pugh, Barney, Magrew, Cuthburt, Dibble and Grub)\n\n• Seven Seas

The previous answer(s) overlook the possibility that 0 balls can be selected from any color (i.e. 11,10, and 8 choices respectively), as long as all three numbers aren't zero. So it's:\n\n(10+1)*(9+1)*(7+1) - 1 = 879

because 3 is considered as a magic number, 9 ias also considered as a magic number (3x3)\nalso 27 (3x3x3)\nalso 81\nalso 243\njust go on multiplying so that u dont have time to ask wrong questions

ok, let's start with the biggest number:\n\n18: 18 can only go with 7 because the nearest perfect square is 25 and other number can put it to 36.\n\nsimilarly, for 17 and 16. they can only go with 8 and 9.\n\nso, so far, we have\n\n18 + 7\n17 + 8\n16 + 9\n\nnow, 2 can only go with either 7 or 14, but since 7 is taken, 2 must go with 14\n\nnow, 11 can only go with 5 or 14, but since 14 is taken, 11 must 5.\n\nnow, 4 can only go with 5 or 12, but since 5 is taken, 4 must 12.\n\nnow, 13 can only go with 3 or 12, but since 12 is taken, 13 must 3.\n\nnow, 6 can only go with 3 or 10, but since 3 is taken, 6 must 10.\n\nnow, 15 can only go with 1 or 10, but since 10 is taken, 15 must 1.\n\nnow, 10 can only go with 6 or 15, but since 15 is taken, 10 must 6.\n\nfor 3, it can go with either 1 or 6 or 13, but 6 and 13 is taken, we only have 1 left.\n\nso....sally goes with 3\n\nin summary\n\n18+7\n17+8\n16+9\n15+1\n14+2\n13+3\n12+4\n11+5\n10+6\n\n\nso...lets summarize what we have\n\n18 + 7\n17 + 8\n16 + 9\n2 + 14\n13 + 12\n11 + 5\n14 + 7

Yes...there will be 7, 8 and 9, but Lucas will not direct them or, in fact, write them. He has handed it over to his trusty sidekick who no one seems to know the name of. I'm sure that he will oversee it though. He is making the TV series - OMG that is going to be awesome - imagine star wars every week - and then in 2010 they will do 7,8 and 9. Go to supershadow.com to see the plot outlines for the those movies.

There is not last number of numbers. In the binary system, or for any system for that matter, you could always add digits to it and the number would increase by at LEAST a power of 10.\n\nInfinity could be the last number, but contrary to popular belief, it is not a number, rather a term stating that something has no end

To this day, it is not known if any odd perfect numbers exist, although numbers up to (10 to the 300th power) have been checked without success, making the existence of odd perfect numbers appear unlikely . There is a project underway at http://www.oddperfect.org/ seeking to extend the limit beyond (10 to the 300th power)\n\nCheck this link for more details:

its impossible because there needs to be either one less sign or one more number look:\n\nin a the order:\n2 * 4 - 6 + 8 /\n              ^there is an extra sign!!
