<human>:  Tim's car goes down in value by $1000 a year. He bought it for $20,000. How much is it worth after 6 years?
<bot>: How much did it go down in value? ** It went down in value 1000*6=$<<1000*6=6000>>6000
How much is the car worth after 6 years? ** So the car is worth 20000-6000=$<<20000-6000=14000>>14,000
#### 14000
