Re: spelling question (english-ish)

The strange part is that (as I understand it, bearing in mind that I don't speak French) "chez [name]" doesn't actually mean "[name]'s house" in French. It means "to [name]'s house" or "at [name]'s house". In other words, "chez" is a preposition mean...

Spoiler:
Edward was born in August. The programmer was born in January, so Edward is not the programmer, and thus Edward is the engineer.

Is the trick supposed to be the extraneous information (54 years old in 1998, 26 weeks older, etc.)?

Re: Interesting Numbers (Whole Numbers)

In primality testing, you actually only need to test up to the square root of n. Also, if an integer's digits sum to something divisible by 3, the original integer must be divisible by 3 and thus composite (unless the integer is 3).
