TWO+TWO=NULL
TWO+TWO=ONE
TWO+TWO=FOUR
TWO+TWO=FIVE
TWO+TWO=SIX
TWO+TWO=NINE
Each one of the above mentioned alphametics, treated separately, has more than one base ten solution. Which one has the most? Which one of them, if any, possess an unique solution in another base or bases?

Thanks Ady.

A, B and C!  Interesting coincidence.

Ady, I doubt you really needed to post, however it is good to know that my programming was without error against your given values.

Charlie was thinking "No leading zeroes" but he overlooked that "zero" was a value for other places.  The software he is using, and what is required re looping is a slow process.  He will come through, I am confident.

I must look at his listing as to how he addressed the multi-base scene though.  There's a lot we can learn from Charlie.
