Well, I was doing some easy algorithm (frobenius method);
and I got an issue, I have a list like this: {a0+6*a1,a1+20*a2,a2+42*a3,a3,...}
And I must get it solved in terms of a0;

I can do this with: solve(list[1]=0 and list[2]=0 and list[3]=0 ...,a1,a2)
and the return is:
a1=−a0/6 and a2=a0/120 and a3=−a0/5040...


The question is can I store those "results" in a list? //sorry if is a dumb question but I couldn't find any example of this.

EDIT:
Someone know how to use variadic functions/programs like:

median(List[,freqlist])

?

// Nspire CAS 1.7 [this is the only version I can have working in computer for free besides ncubate]

Can you store the result of solve in a string?

Actually I need it as values, however, maybe i can get through this with some workaround;
So If I do this, "solve()=:a", it is stored as string ?

Sorry If I was ambiguous, but I didn't ask how to use median,
What I am looking for is: to create a function which can be called like->

f(x)

and

f(x,y)
// Actually this is polymorphism for OO languages or variadic functions as called in ansi C.
