Hi! In a theoretical sense, they can be whatever you want. So if V1=10V and V2=20V, then, as an unscaled summer, V0=-30V. And as an average circuit, V0=-15V. However, in a physical circuit, the limits of the inputs and the resultant output would depend on what physical OpAmp you end up using. For example, a typical 741 OpAmp can only output up to around +/-20V (see LM741A datasheets). Hope that helps! 😁
