Chemistry in Grade Three is the common sense of chemistry learning. Although it belongs to science, it is still partial. Poor mathematical foundation does not affect the study of chemistry, and its calculation problems are not all about the use of mathematical knowledge, even if it is used, it is mostly primary school mathematics. So take it easy. However, there are many element symbols, chemical formulas and basic concepts to be memorized in chemistry learning. Only by mastering these chemical languages can we really learn chemistry well. Learning chemical language is a bit troublesome, but I believe you can! Don't worry, have confidence in yourself! Confidence is the beginning of success!
