### Operational Amplifier Circuit Analysis

#### Problem Statement
For the op-amp circuit shown, find the output voltage \( V_o \) in terms of the input voltages \( V_{i1} \), \( V_{i2} \), and \( V_{i3} \). Hint: Superposition.

#### Circuit Description
The circuit diagram consists of three operational amplifiers (op-amps) with different input voltages \( V_{i1} \), \( V_{i2} \), and \( V_{i3} \). The resistances in the circuit are either 10kΩ, 20kΩ, or 30kΩ as detailed below:

1. **First Op-Amp Configuration**:
    - Non-inverting input is \( V_{i1} \) through a 10kΩ resistor.
    - Inverting input is connected to a 10kΩ resistor that goes to ground.
    - Feedback resistor of 10kΩ.

2. **Second Op-Amp Configuration**:
    - Non-inverting input is \( V_{i2} \) through a 10kΩ resistor.
    - Inverting input is through a 20kΩ resistor and connected to ground.
    - Feedback resistor of 10kΩ in parallel with a series connection to the next stage.

3. **Third Op-Amp Configuration**:
    - Non-inverting input receives the output from the previous op-amp stage and \( V_{i3} \) through a parallel configuration of resistors.
    - Inverting input receives the combined input through a 10kΩ resistor.
    - This sets the final output voltage \( V_o \).

#### Detailed Diagram Analysis
- **Node Analysis at Each Op-Amp**:
    - For the first op-amp, utilize voltage divider and feedback concepts to find the intermediate outputs.
    - For the second and third op-amps, the superposition principle will be essential in analyzing the contributions from each voltage source \( V_{i1} \), \( V_{i2} \), and \( V_{i3} \).

By applying the principles of superposition and circuit analysis, compute \( V_o \) by considering the individual effect of \( V_{i1} \), \( V_{i2} \), and \( V_{i3} \) on the output, and then summing these effects.

This problem encourages a comprehensive understanding of
