李家宝老师在《单项式除法中一个值得商榷的问题》(《中小学数学》(初中版)2014年第9期)一文(简称“李文”)中,对单项式的认识及单项式在除法运算式中的书写方式提出了自己的观点.他认为“从单项式的定义上来看7x~3y的意义,它本质上是表示7,x~3与y之乘积,它是由代数式7×x~3×y的书写规则约定俗成而记作7x~3y.因而无论是从本质上还是从形式上说,28x~4y~2÷7x~3y都应表示28×x~4×y~2÷7×x~3× In his article ”A Problem with Monistic Grading“ (”Elementary and Middle School Mathematics“ (No. 9, 2014)), Professor Li Jiabao recognized the monomials and the division of monomials The way of writing in arithmetic expression puts forward his point of view.He thinks ”The meaning of 7x ~ 3y from the definition of monomial is essentially the product of 7, x ~ 3 and y, which is composed of algebraic 7 × x ~ 3 × y rules of writing conventional and recorded as 7x ~ 3y. Therefore, whether in essence or from the formal terms, 28x ~ 4y ~ 2 ÷ 7x ~ 3y should be said that 28 × 4 × y ~ 2 ÷ 7 × x ~ 3 ×
