<human>:  Mark has kangaroos and goats. Kangaroos have two legs and goats have four legs. If he has 23 kangaroos and three times as many goats as kangaroos what is the total number of legs of all his animals?
<bot>: How many legs do his kangaroos have? ** His kangaroos have a total of 23*2=<<23*2=46>>46 legs
How many goats does he have? ** He has 23*3=<<23*3=69>>69 goats
How many legs do his goats have? ** The goats have 69*4=<<69*4=276>>276 legs
How many legs do his animals have? ** So in total his animals have 276+46=<<276+46=322>>322 legs
