Simulation with Multisim problem

[kidd]

This is the value after i calculate ,but use multisim to simulate this circuit,i get a answer different completely with the calculate answer.Example the Vout,also is most importent value,the calculate answer is -2.1V,but the answer of simulation is possitive value!y will like this?It i use the wrong way?The value of Vin the lacturer want us input 0V,so i connect to ground.I have attached the msm file of multisim and the graph with answer i calculate,wish got ppl can help me...most important is can let the Vout same with value of calculate,equal -2.1V.thank you very much...
