Voltage multiplier using operational amplifiers

[botthe.]

Hi! I have to design a circuit whose output should be the product of the two input voltages. The voltages can vary from -3 to +3 V and max. frequency is 10kHz. I am not supposed to use any analog multiplier IC. I thought of the log-antilog technique but it won't work as I have negative inputs. There was a circuit using MOSFETs in wikibooks but that again works only for positive voltages. There was another one using BJTs but again had a limitation of input voltage << 25 mV.?Opamps provided are TL-082 and uA-741. Any suggestions????
i have very less time to finish this circuit..

A common way to do analog multiplication is with a Gilbert Cell.
