"If you connect the two op-amp inputs together to create ex-
actly zero differential input signal, the output will usually
saturate at either V + or V− (you can’t predict which). The
difference in input voltages necessary to bring the output to
zero is called the input offset voltage, V OS"
So with ΔU = Uos, I get zero output. ΔU = Uos = U1 - U1 + Uos means that some term didn't get cancelled out...
