RE: Little explorations with the HP calculators
Ok while the other problem is still open (1), a new one.

given 4 different positive integers: a, b, c, d .

Find all the quadruplets where all the terms are smaller than 1000, that satisfy the following identify

(a+b) / (c+d) = (a-b) / (c-d)

(I did not attack it yet).

Bonus: do the same for positive integers: a, b, c, d where there are at least 3 different integers.

Once again, I do not see how those can be list/string challenges, if someone has an idea, he is welcomed!

(note1) or better, I think that getting the information whether Alan is ahead of Bob for the entry N should be not that complicated unless I am mistaken.

Wikis are great, Contribute :)
