101 = 102 - 1

this seems to be more straight forward rather than the square of 10 solution.. ;)

move the - from the rhs to lhs sign

That wouldn't be moving a "numeral" as required...

What about 101 - 10 = 21 (in base 3) <!-- s:?: --><!-- s:?: -->

You would count 0, 1, 2, 10, 11, 12, 20, 21, 22, 100, 101 etc... <!-- s:lol: --><!-- s:lol: -->

This is the right answer. I am thinking the same.
