CircuitLab example wrong?

Hello,

regarding this example provided by Circuitlab:

https://www.circuitlab.com/circuit/me84mf/op-amp-non-inverting-amplifier/

It states: "Since the voltage at the inverting input is set to 1/10th of V(out) by the resistor voltage divider ratio R1/(R2+R1), V(out)=R1/(R2+R1)*V(in)."

Obviously the formula for V(out) is wrong.

I thinks correct is "V(out)=(R2+R1)/R1*V(in)"

Please comment. Thanks.
