The code below gives an empty Ans although it is clear that the solution is 0,0,0,0.
syms a b c d
res = solve(a+b,a+b+c,a+b+c+d,a)
Hence why do we get an empty answer?

sol = solve([a+b==0,a+b+c==0,a+b+c+d==0,a==0],[a b c d]);
sol.a
sol.b
sol.c
sol.d
Best wishes

Thanks a lot, I didn't know that a square bracket would make all the difference.
