Yes, high numbers really don't help much. You don't even need to buy food. But if no one uses advanced mathematics, you can't even work out this problem. Not to mention "empty talk" such as "advanced mathematics is the foundation of all disciplines in the university" and "it can cultivate your xx thinking", and not to mention its application in civil engineering and economy. Just give a few examples of my major. When you open the picture on the web page, I wonder if you have thought about huffman encoding and matrix series; When you turn on the player to play music; Have you ever thought about Labourasse transform and Fourier transform? When you get lost and open the mobile phone to locate the map, you never thank relativity and linear algebra; When you think high numbers are useless, you want to vomit. When you open Baidu to type questions, you may forget fuzzy mathematics and definite integral ... Maybe in life, you don't need high numbers at all, but you must use products made by others with high numbers and other knowledge. So please respect science and don't judge the world by your own feelings.
