数学符号是人们对客观事物运动规律的最直观、最简明的表达方式,是交流与传播数学思想的媒介.它能深刻、简练的表述、揭示一些数学内容.代数就是引用了较好的符号体系,依赖于符号而建立起来的,因此,对数学符号的正确认识并研究它的教学就显得非常重要了.小学的数学符号除了单一的“+、-、×、÷”和分号等符号外,几乎没有别的符号,而在初中的数学里却采纳了相当大的符号体系,初中数学里所建立的这些符号,不论从基础知识,还 Mathematical notation is the most direct and concise expression of the laws of people’s movement of objective things and is the medium of communication and dissemination of mathematical ideas.It can profoundly and concisely explicate and reveal some mathematical contents.Algebra is a reference to a better symbolic system , Depends on the symbol to establish, therefore, the correct understanding of mathematical symbols and study of it is very important.Mathematical symbols in primary schools in addition to a single “+, -, ×, ÷ ” and semicolons There is almost no other symbol outside the symbol, but in junior high school mathematics it adopts a rather large symbol system. The symbols established in junior high school mathematics, no matter from basic knowledge
