| It's not true for decimal or hex, and they are not valid octal expressions. Logarithms, maybe?

| Think more visually. Pattern recognition. |

| I can see a pattern in the first two numbers, and a portion of the pattern in the sum. But I cannot make the connection of the addition. My mind is tired, so I shall admit defeat.

| 32587 + 14569 = 448537
In the first two numbers: the first and second digits add up to the third digit; the first and third digits add up to the fourth digit; the second and third digits add up to the fifth digit.
In the sum, the first digit and the number composed of the second and third digits add up to the number composed of the fourth and fifth digits; but I don't think that is relevant. That's where I quit.

| Here's one for you guys. Hang on to your asses, because it involves statistics and probability.
You're on a game show.
There are three doors, one of which opens to reveal the prize. The other two doors have nothing behind them.
You pick one of the doors, let's say door number one.
The host then opens door number two, revealing nothing - a loser.
You are then given the option of staying with your original selection, door number one, or changing your selection to door number three, the one not opened by the host.
Are your odds of winning improved by changing your selection to door number three? |

| Ah yes, the problem above is the famous Marilyn Vos Savant dilemma which generated more controversy than any other issue she tackled. - _Howard wrote:

| Yes, the Monty Hall puzzle fools a lot of people. The key point, that a lot of people overlook, is that when he opens a door, he knows it's a loser, he doesn't open one at random.
So when you work it all out, you're right to switch. Poor Marilyn got it right, and was hammered by mountains of mail telling her she'd got it wrong.

| Yes, Monty gets the credit but poor Marilyn took all the heat. From a lot of PhDs and mathematicians who ignored the fact that Monty didn't open a door at random, but opened one he KNEW contained a goat (or whatever the gag gift was). Sorry Howard, but this puzzle is famous as a case where statistics and logic diverge from common sense and received wisdom. |

| I know that the three-doors puzzle is famous. That doesn't mean everyone agrees with Vos Savant. I was just asking what your opinions were, not what you had read. I have reason for not being quite sure that dear Marilyn is right. - NoCoPilot wrote:

Okay, here's your next clue. Which part of "I quit" did you not understand? |

| four(2) could had indicated coordinates, but I couldn't make any sense of that, so I went with a power.

| George Burns and Morgan Freeman both did it, but they never killed anybody.
What did they do? |
