Then subtract 6 from that number to find the number of bridge trolls: 24 trolls - 6 trolls = 18 trolls. Then divide that number by 2 to find the number of plains trolls: 18 trolls / 2 = 9 trolls. Then add the number of trolls she saw in each location to find the total number: 6 trolls + 18 trolls + 9 trolls = 33 trolls.
The final answer: 33.
