读了《中小学数学》(上旬)2015年第1、2期苏莹的《解稍复杂方程的疑惑和感悟》一文,深感作者勤于钻研的精神值得学习,并对作者的疑惑进行了认真的思考、分析,现谈谈我对“疑惑”的理解和感悟。引发作者疑惑的是解下面这一方程:0.95÷4x=0.19,作者是这样解方程的:0.95÷4x=0.194x=0.95÷0.194x=5x=1.25从中可以看出作者在解方程时是把4x看作一个 Read the “primary and secondary mathematics” (early) in 2015 the first and second period in 2010 Su Ying “solution slightly complex equation doubts and insights,” a text, the author diligently study the spirit worth learning, and the author’s doubts were Serious thinking, analysis, now I talk about the “doubts ” understanding and perception. The author is puzzled to solve the following equation: 0.95 ÷ 4x = 0.19, the author is the solution to this equation: 0.95 ÷ 4x = 0.194x = 0.95 ÷ 0.194x = 5x = 1.25 It can be seen from the equation 4x as one
