What is the cardinality of R2?
Seems like it should be a fairly simple to explain, yet I'm stuck beyond belief.
Attempt:
R2 = R x R
Now we have shown that the |R| = | [0,1] | but then when I think of possibly combining that fact I'm still somewhat in the same place. How do I "explain" the size of R2?
