Mathematics requires students' thinking very much, because knowledge will become more and more difficult, and at the same time, the requirements for mathematical thinking will become higher and higher. Many students can't persist in thinking, studying and analyzing, because people are lazy, so they only leave their studies on the surface. And many people don't want to think, but mathematics takes time to think, so that we can concentrate more on mathematics learning, and it also needs great efforts to complete. People who think that mathematics is difficult must have not laid a good foundation and have no quick and sensitive response.
Many people think that chemistry is difficult because it is different from other sciences, because chemistry needs to remember a lot of knowledge, and learning chemistry needs to have enough basic knowledge and skills. It is also perceptual knowledge, but it is expressed by some chemical equation element symbols. These contents need to be remembered, so we must lay a good foundation when studying chemistry and pave the way for future study.
In addition to knowledge points, chemistry has many comprehensive knowledge points, which require the ability to analyze problems, which fundamentally determines that chemistry is a difficult subject to learn. Moreover, chemical balance is also a difficult problem, so there are still many variables. Chemistry is also more difficult because of many variables. There is also a lot to remember in chemistry, and the content of memory is not only a few formulas such as mathematics and physics, but also chemical notes are more troublesome about reaction mechanism, physical properties and chemical properties.
