按照中等代数教程的某些章節來看,習題課本中現有的練習還是需要改善的,因為這些習題大抵都是码於同一類型。特別是有關二項式定理方面,所設習題多半是按照一般項的公式去求展開式中含某文字某次乘方的某項,就練習的性质上来说,那是極其不自然的;並且特別是引起了某些部分的重複。共實關於牛頓二項式可以编入一些有趣的习题,使二項式定理應用到數學上各種不同的部分裏去。 According to some sections of the intermediate algebra tutorial, the existing exercises in the problem textbooks still need to be improved, because these problems are mostly coded in the same type. Especially with respect to the binomial theorem, the set of exercises is mostly based on the formula of the general term to find an item in the expansion that contains a word or a power, which is extremely unnatural in terms of the nature of the exercise; and In particular, it caused repetition of certain parts. Co-realistic Newton binomials can be incorporated into some interesting exercises to apply the binomial theorem to various parts of mathematics.
