排列组合问题一直是高中数学教与学的难点。本文结合实例,详细讲解了排列组合中的相邻问题捆绑法,不相邻问题插空法的解题策略。 The problem of permutation and combination has always been a difficulty in mathematics teaching and learning in high schools. In this paper, with examples, we explain in detail the adjacent problem binding method in permutation and combination, and the problem-solving strategy of interpolation method in non-adjacent problems.
