$\bf A \cup B\implies \textit{sets A and B combined, with no repeats}\
A \cup C\implies \textit{sets A and B combined, with no repeats}\
A \cap B\implies \textit{numbers found in A and at the same time in B}\
A \cap C\implies \textit{numbers found in A and at the same time in C}\
B \cap C\implies \textit{numbers found in B and at the same time in C}$
