So you know from algebra I can't actually solve this. There may be multiple solutions to this. What would I have to do to change my code? And the answer is fortunately not a lot.
我解不出来方程,可能会有多组答案,我需要怎样修改我的代码呢?,很幸运的,答案是不用修改很多。
The exams will be multiple choice and short answer, fill in the blank, that sort of thing.
题型分为单项选择,简答,还有填空之类的
