Hi yall, I was just reading a book on set theory and I came across this definition of an ordered pair:
[tex]\langle a,b\rangle \equiv \lbrace \lbrace a,1 \rbrace, \lbrace b,2 \rbrace \rbrace [/tex]
I think this is a really ingenious way to define an ordered pair but I was wondering are there any other, more intuitive, ways to define an ordered pair?
edit: fixed the pointy brackets thanks to Hurkyl
