I feel that this year's pyramid problem is not as difficult as last year's Venus problem. In practice, Venus Natti is relatively simple, but the amount of calculation is huge, even for a person with a strong amount of calculation like me, it will take several minutes. But the pyramid problem, people who often brush the questions can easily see the answer, even without calculation, because it gives a very regular quadrilateral pyramid.

Let's talk about 19' s brokeback Venus. This kind of question first appeared in the college entrance examination paper of senior one. Without Arabic numerals, there are only various proportions. It may not be difficult to list this formula by calculating a decimal through various proportions, but as long as you work out this answer, you should not only remember the decimals of commonly used numbers, such as root number three, root number five and root number seven, but also need a huge operation. This operation is similar to the physics experiment in the university. Without a computer, it will take at least three to five minutes, which is why this problem really stumbles a large number of people. Senior high school mathematics pays more attention to operation methods. The students are far behind in the calculation exercise. I remember when I was in high school, every time I met a problem with a large amount of calculation, my class would boo, but when I met some special ways of thinking and solving problems, everyone's brains turned faster than anyone else, which was more terrible than beating chicken blood.

Let's look at the pyramids. Maybe candidates will be really confused when they see this question, but you must look at the question carefully when you take the college entrance examination. When you finish reading the question, you don't even need to draw a picture. You will know that this is a very special quadrilateral, and the area of the side triangle is equal to the area of the bottom. This condition tells you a lot. Even a person who does a lot of math problems will often encounter such quadrangles in geometry problems, and it is easy to calculate their height-to-bottom ratio, and there is no complicated calculation, which is relatively easy, even to send sub-problems.

To sum up, the problem of broken arm Venus is more difficult and needs more calculation. And this year's students have already experienced this kind of question, so they must be prepared. So the pyramid problem is not as difficult as last year's Venus problem.
