Hi, "Outer" does what you want, e.g: A={1,2,3}; B={40,50,60,70}; Outer[Plus,A,B]//Flatten hope this helps, Daniel changbo wrote: > I want to make a function "f", its domain is every thinkable two sets, and the result is {a+b | aâ??A,bâ??B} for A,B. > > ex) A={1,2,3}, B={40,50,60,70}, > then I have f[A,B] as > {41,42,43,51,52,53,61,62,63,71,72,73}. > > How can I construct function "f"? Let me know the source.. Thank you very much >
