... 6. Even odds. Let E stand for the set of all even natural numbers (so E = {2, 4, 6, 8, . . . }) and O stand for the set of all odd natural numbers (so O = {1, 3, 5, 7, . . . }). Show that the sets E and O have the same cardinality by describing an explicit one-to-one correspondence between the two s ...

If the result was zero, she stopped. • (b) If it wasn’t zero, she took the reciprocal. The result always had a whole number part so she went back to ...
