This circuit amplifies the input signal without inverting it, multiplying the voltage by 3 using an operational amplifier. The op-amp tries to keep the same voltage at its two inputs. One of them is at the input voltage, so for the other to be the same, there must be a voltage drop across the 1 kΩ resistor equal to the input voltage. The 2 kΩ resistor has the same current, so the voltage drop must be twice as large by Ohm's law. Thus the output voltage equals the input voltage plus 2 times the input, or 3 times the input in total.
