Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

So I wont be taking part

For example, the first puzzle can be solved using PHP like this:
<?php
for ($i=1; $i<1000; $i++) {
if ($i % 5 == 0 || $i % 3 == 0) {
$total += $i;
}
}
echo $total;
?>

So far quite easy, but I'm seeing some very hard problems.

I solved a few of those some years ago, but it got very hard very fast :)

You pair will be in nerd heaven

back to my "hello world" tutorial....

Finished the first 10!
Although I had to google some algorythms, since my CPU started melting at brute forcing question 5

calculating 2^1000 is also a challenge for the average cpu.
I remember writing a script for that once in Turbo Pascal about 15 years ago, but then it was limited to 256 digits.

I should go back to work..

Or in binary (you could calculate that in your head):

Finished 17 of em so far
I love it, but I seem to be very inefficient all the time. My math skills are far behind. It's not very important for a web developer either.

I solved 19 many years ago, but got bored. They are getting harder very fast, and my math skills aren't what they used to be (and even what they used to be is probably not enough ... :)

I think it depends on what language you use. There are some math oriented languages that seem to be born for this kind of stuff.
I like the forum pages. Some of the solutions are just insane.
