Question 1: let a be an unknown number,
Then: (a) + 4 = (a + 8) - 4 = [(a + 4) / 4] × 4 = [4 × (a + 4)] / 4
Then (a) + (a + 8) + [(a + 4) △ 4] + [4 × (a + 4)] = 175
25A = 175, so a = 24
So (24) + 4 = (32) - 4 = (7) × 4 = (112) △ 4
Question 2: (2 * 2 * 2) + 2-2 = 8
2+2+2+（2÷2）=7
（2*2）+2+2-2=6
2+（2÷2）+（2÷2）=4
2+2-2+（2÷2）=3
2+2-2-（2÷2）=1
Finish the work. It's so detailed. It's a pity that it's not divided

4. Who can work out this problem Leo Tolstoy, the great master of Russian literature in the 19th century, once wrote such a story in his work "does one need a lot of land?" There was a man named bahome who went to the grassland to buy land. The chief who sold the land offered a very strange price of "1000 rubles per day", which means that as long as he started from the specified place at sunrise and returned to the starting point before sunset, all the land enclosed by the route he took would belong to him. If he could not return to the starting point before sunset, he would not get any land, It costs 1000 roubles Bahome felt that this condition was good for him, so he paid 1000 rubles. The next day, at dawn, he quickly strode forward on the grassland. He walked a full 10 Russian miles (1 Russian mile ≈ 1.0668 km) before turning left. Then he walked a long time before turning left again. After walking another 2 Russian miles, he found that it was not early, and he was still 15 Russian miles away from the starting point, So I had to change direction and run straight to the starting point Finally, he arrived at the starting point on time, but died of overwork and spitting blood How many Russian roads did bahome walk on this day? What is the area of land surrounded by his route
