What do these symbols mean? (need to 'make stmts true')

Hi folks,
I am helping my brither with algebra, but I am not familiar with those symbols in the answer section. What do they mean? How should we approach this problem? I'm used to seeing equations in algebra, not this.

These symbols should clearly explained in his book - look into glossary section.

or look into this web-site

Re: Help! What do these symbols mean?

a) What's to the left of the symbol "is a subset of" what's to the right of the symbol.
b) What's to the right of the symbol "is a subset of" what's to the left of the symbol.
c) What's to the left of the symbol "is NOT a subset of" what's to the right of the symbol.
