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.

Each problem has been designed according to a "one-minute rule", which means that although it may take several hours to design a successful algorithm with more difficult problems, an efficient implementation will allow a solution to be obtained on a modestly powered computer in less than one minute.

I thought you guys might like this site and we could share the methods you used to achieve the answer. Do not post the answers though. Have fun!

**Problem 1**

three = 3 five = 5 sum = 0 x=1 Loop,999 { isnatt := x/three isnatf := x/five Stringright,iszerot,isnatt,1 StringReplace,isnatf,isnatf,00000 Stringright,iszerof,isnatf,1 if iszerot = 0 { sum := x + sum x++ continue } if iszerof = 0 { sum := x + sum x++ continue } x++ } msgbox %sum%

**Problem 9**

n = 1 m = 1 loop 1000 ;n loop { loop 1000 ;m looop { if (m > n) break a := (n*n) - (m*m) b := 2*m*n c := (n*n) + (m*m) total := a+b+c if total = 1000 { product := a*b*c msgbox product=%product% a=%a% b=%b% c=%c% } m++ } m := 1 n++ }

I will post more answers later.
