Hi, A = {1, 2, 3}; B = {40, 50, 60, 70}; f[a_, b_] := Flatten[a + # & /@ b] and f[A, B] gives {41, 42, 43, 51, 52, 53, 61, 62, 63, 71, 72, 73} Regards Jens 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"?
