1.Find the minimum sum of three 3-digit primes, using all non-zero digits.

2.What is the smallest possible sum of primes which are formed using each of the digits 1 through 9?

I will not argue whether an interpretation other than mine makes sense, irrational;

I should have worded it better , like "all** the** non-zero digits", or "using 9 **distinct **non-zero digits"** , **but clearly I had the **999** result in mind**.**

If anyone solved , like **" primes, all using non-zero digits",** **ok** ,so be it. It just was not my intention.
