Alright guys,
My last math challenge has not been solved, but I am getting tired of waiting, so here is another challenge for you. Remember, the winner gets a candy bar!! (Or another prize of equal or lesser value if you so choose)
You are playing a game in which it is possible to score 4 points or 9 points. Which scores are not possible?
Maybe if I make this post bright and colorful, someone will notice it…

K, guys. I posted this math challenge a long, long time ago. Maybe even before some of you were born. Anyhoo, although I have had people tell me that they are working on it, I have yet to see someone solve it. You could be that person! I decided to re-post it, in case you forgot about it.
SOMEONE PLEASE SOLVE THIS PROBLEM SO I CAN POST A NEW ONE!!!!!!!!!!!!
Suppose I starting writing the numbers from 1 on up, as follows:
123456789101112131415161718192021222324252627282930313233…
If I had an infinite amount of time and patience (In fact, I have neither!) I could keep this string of digits going forever.
What I want to know is, what is the 2-millionth digit in this string of numbers?
Happy Counting!!
p.s. Take a minute or two to think about this problem before you try it. It can be done rather quickly.

Alrighty, then. The long division problem was solved, congrats to Courtney! In celebration, I’m posting another tricky problem for all of you who were so close to getting that last one. Here goes:
