Hi Tatyana, I can think of the following solutions: 1. If your classes are of different types say Integer and Real, you could use f[a__Integer,b__Real]. 2. Use f[{a__},{b__}], of course you will have to write the brackets later. 3. Use f[a__,x,b__] where x is a symbol you don't use otherwise. (By the way if you define f[a__,x,b__]:=a/b, you get an amusing result.) 3.a) (Variant of 3.) f[a__,x_Symbol,b__] 4. f[a__][b__] Of course one could go on for a while,but I think there should be something for you. Pick your choice.
