求解不等式组的解集在初中数学中虽不属难点内容,但仍就给很多同学带来麻烦,一些同学不能借用数轴准确得出解集,一些同学即使能得出解集,在解题过程中也是耗时又耗力.下面介绍一条操作简单、能快速写出不等式组解集的口诀,希望能给同学们带来方便.求不等式组解集的口诀:“同大大大,同小小小,大小小大中间架, The solution set of solution inequality group is not difficult content in junior middle school mathematics, but it still brings troubles to many students. Some students can’t use the axis to get the solution set accurately. Some students even get the solution set in the process of solving the problem. It is also time-consuming and labor-intensive. Here’s a simple operation that can quickly write out the inequalities group solution set, hoping to bring convenience to the students. Find the inequality group solution set: ” with big big, same small Small, small middle frame,
