Special terms for high school mathematics:
Sets and the relationship between sets: the intersection of sets is the empty set, non-empty set, and set equality
don't go away
I'm not writing a math paper haha
Next, I will explain these terms in easy-to-understand terms.
The so-called two sets: Two sets represent two individuals, for example, one is A's feelings for B and the other is B's feelings for A.
The so-called intersection of sets is the empty set: it means that there is no relationship between two people AB. If you don't love me, I won't love you either.
The so-called non-empty: at least one of the two AB has developed feelings for the other
The so-called set equality: AB two people, you love me and I love you, everyone is happy.
Now you understand
This article introduces how Gu Jing, an English and homeroom teacher who combines beauty, intelligence and talent, gradually changed the relationship between her and rookie math teacher Jiang Yiyi from an empty set to a non-empty set and finally to equality.
