00=x
0x=0
x can be any value, therefore 00 can be any value, and is indeterminate.
10=x
0x=1
There is no such x that satisfies the above, therefore 10 is undefined.
Is this a reasonable or naive thought process?
It seems too simple to be true.
Answer
In the context of limits, 0/0 is an indeterminate form (limit could be anything) while 1/0 is not (limit either doesn't exist or is ±∞). This is a pretty reasonable way to think about why it is that 0/0 is indeterminate and 1/0 is not.
However, as algebraic expressions, neither is defined. Division requires multiplying by a multiplicative inverse, and 0 doesn't have one.
