I have a pretty good grasp of entanglement and superposition, but I am specifically confused about how correct calculations can be made. I have to give a presentation on quantum computing for class and I am confused about this aspect.

If you have an array of entangled qubits, I understand that they can represent all combinations of 1's and 0's at the same time. But, when you measure these qubits the wave function collapses leaving them in a state representing 1 or 0. Since this is true, how does the qubit being in superposition help if measurements while the system exists as all possible combinations at the same time cannot be taken? Wouldn't the result be any random combination out of the 2\^n possible? If I'm not mistaken it seems like the correct calculation will always exist, but there just is no way to extract it.
