I am a master of mathematics. In fact, the math problems in primary schools are quite simple. I won the first prize in the previous Mathematical Olympiad, but my thinking in mathematics is different from that in mathematics. Many people find it difficult for me not to change my mind.

Mathematics in high school is quite difficult. In addition, compared with primary schools, there are contents of junior high schools. High school mathematics is based on junior high school mathematics, and has little connection with junior high school mathematics. High school mathematics will introduce many brand-new concepts, and there are many things that do not follow normal thinking. Solid geometry, inequality, sequence and other contents are the most difficult part of high school mathematics, and also the focus of college entrance examination. Higher mathematics in universities should be based on high school mathematics, so high school mathematics is not the most difficult part of mathematics.
