If you see where I put each digit of the base 9 number I converted into the equation, you should be able to do the same things with the two numbers you just posted. (I put each digit as the first number inside each set of parenthesis.) I would go through it for you, but I need to get going. I'll stop by later to see if you still need help.

The way to convert 31.234 in base 9 to base 10 would be to do the following: (3 x 9^1) + (1 x 9^0) + (2 x 9^(-1)) + (3 x 9^(-2)) + (4 x 9^(-3)) = (3 x 9) + (1 X 1) + (2 x 1/9) + (3 x 1/81) + (4 x 1/729) = 28.2647 Basically, you convert numbers to base 10 from any base B by taking the summation of each number left of the decimal multiplied by B to the power of its position left of the decimal minus one and the numbers right of the decimal multiplied by B to the negative power of its position right of the decimal. I hope that's confusing enough for ya!

I have done some promotional treasure hunts in my area with a group of friends. We have been doing one that comes out in our local newspaper every February, and we finally found it this year. The prize included a pass to some local golf courses and a membership to a gym. We also won two separate treasure hunts put on by a local radio station this summer. Both treasure hunts involved finding a "mini Xbox 360" which were turned in for real Xbox 360's. Everybody in our group is a geocacher, and our geocaching experience really helped us find the second mini Xbox as it was hid in a location where one of our local multicaches begins. I personally believe that we are successful mainly because we find the enjoyment in treasure hunting from the thrill of the hunt, not in the spoils. I think we'd do a treasure hunt even if the prize was stick of gum!
