(7) In a 6×9 square, the starting point is at the lower left corner and the ending point is at the upper right corner. From the starting point to the ending point, you can only go from bottom to top, left to right, and ask how many different ways there are.

(8) There is a strange village with a total of 100 people, men and women, men tell the truth and women tell lies. One day a stranger came to this village and asked the villagers, "How many women are there in your village?" The first villager said 1, the second villager said 2... and so on, the hundredth villager said 100. So how many women are there in this village?

Answer: 99 Suppose the first villager says 1 is right, then 2, 3, 4... 100 villagers are all wrong, the number of men in the village = 100-1 = 99, 99 out of 100 villagers If a man tells the truth, then it is the exact opposite of what the first villager said, so the first villager is a woman.

Suppose the last villager says 100 are right, then villagers 1, 2, 3... Then it's the exact opposite of what the hundredth villager said, so the hundredth villager is a woman.

By analogy, if the 99th villager says 99 is right, then villagers 1, 2, 3...98, 100 are all wrong, the number of men in the village = 100-99 = 1, and there are 100 villagers in the village. 99 lied, because the 99th villager was right, so villagers 1, 2, 3...98, 100 (except the 99th villager) were all women.
