assistant
How many trees does James cut down by himself? ** He cuts down 2*20=<<2*20=40>>40 trees by himself
How many trees does each of James' brothers cut down? ** Each of his brothers cuts down 20*.2=<<20*.2=4>>4 fewer trees per day
How many trees do each of James' brothers cut down? ** So they each cut down 20-4=<<20-4=16>>16 trees
How many trees do James' brothers cut down in the next 3 days? ** So for the next 3 days they cut down 20+16*2=<<20+16*2=52>>52 trees per day
How many trees did James, his brothers, and his brothers' brothers cut down? ** So they cut down 40+52*3=<<40+52*3=196>>196 trees
