What's going on with me?

4-30-07 - I�m so sick of the fact that the stupid computer parts I bought 8 months ago don�t form a functioning computer. I have no idea what�s wrong and I refuse to pay someone $129 for 5 minutes� worth of work to tell me something I already know. This is quite frustrating.

If you�ve never played Wii tennis before, find someone that has it and four controllers, get a couple friends, and go play it. It�s amazing. I realized how awesome it was on Christmas Eve, but I�ve been playing it with different groups of people lately and it�s mucho fun.

As with the past couple updates, nothing really new is going on. I�m constantly busy, not really in a routine, but not a whole lot worth writing about is going on. That�s kinda depressing.

I did, however, go to karaoke a few nights ago. A couple friends talked me into singing something by Pearl Jam, so I put �Jeremy� in the queue. As soon as I sat down, I thought about it and asked if it was really an appropriate song to sing a week and a half after the Virginia Tech thing. They said to do it anyway, so I did. Yippee.

4-10-07 - Pick any three digit number in which the first and last numbers are different. Reverse the order of the numbers. Subtract that number from the original number (or vice versa, if the reversed one is larger). We�ll call this the �new number.�

Take the new number and reverse the order of the digits. Add this reversed number to the �new number.� What do you get?

Boredom led to my deciding to prove this algebraically. The proof is below:

Let ABC be the original number (<= is �less than or equal to�)
where A > C
where 0 < A <=9
where 0 <= B <=9
where 0 <= C < 9
let D = A � C
therefore 1 <= D <= 9

ABC = 100A + 10B + C
Reverse it: 100C + 10B + A
Since A > C, the original is larger. Subtract them:
100A + 10B + C � (100C + 10B + A) = 99A � 99C = 99(A � C) = 99D

99D = 100(D � 1) + 90 + (10 � D) (Don�t ask how I figured this out, I just did.)
Reverse it: 100(10 � D) + 90 + (D � 1)
Add them:
100(D � 1) + 90 + (10 � D) + 100(10 � D) + 90 + (D � 1) =
101(D � 1) + 180 + 101(10 � D) =
101D � 101 + 180 + 1010 � 101D =
