I'm trying to solve a cryptarithm that must meet all of the following conditions:
one + one = two
seven is prime
nine is a perfect square
More specifically, i'm trying to find the following:
Firstly, can someone explain the first condition (one + one = two) and how it fits in with the other conditons? Is this a sort of cryptarithm within a cryptarithm that must also stay true to the other conditions?
Secondly, what approach should I take to logically deduct the solution?
