```expr = a + b - c + f - g[a]/g[b];

soln = List @@ expr

{a, b, -c, f, -(g[a]/g[b])}

Plus @@ soln == expr

True

Total[soln] == expr

True

Hi!

I want to separate a Mathematica expression written as a sum into
separate terms
E.g. for

a+b-c+f-g[a]/g[b]

I want to get a list

{a,b,-c,f,-g[a]/g[b]}

Is there a simple way to do this?

Thanks,
