Human: Digimon had its 20th anniversary. When it came out John was twice as old as Jim. If John is 28 now how old is Jim? Assistant: 
How old was John when Digimon came out? ** When Digimon came out John would have been 28-20=<<28-20=8>>8
How old was Jim when Digimon came out? ** So Jim was 8/2=<<8/2=4>>4 years old
How old is John now? ** That means John is now 4+20=<<4+20=24>>24
