我们知道方程在中学数学中占的比重较大,从初一到高三都有,一般给中学生留下很深印象,提起代数自然想到方程。这也不奇怪,从历史上看代数的发展和方程分不开,并且方程历史悠久,三千六百年前就有相当于今天的方程“x(2/3+1/2+1/7+1)=37”,在十九世纪以前就是把代数理解为方程的科学.因此方程在中学代数教学中是公认的中心问题之一.但是关于解方程的概念,不少人说不清楚,现就几个具体问题进行讨论.
We know that the equation accounts for a large proportion of high school maths. From the first to the third highs, it usually leaves a deep impression on middle school students, and naturally comes up with the algebra equation. This is not surprising. Historically, the development of algebra has been inseparable from the equation, and the equation has a long history. Before the age of 3660, there was an equation equivalent to today’s equation of “x (2/3 + 1/2 + 1/7 +1) = 37 ”, which was considered as the science of equations before the nineteenth century, so the equation is one of the central problems in algebra teaching in middle school.However, many people are not clear about the concept of solving equations, A few specific issues are discussed now.
