... There is a way of constructing the answer, also, by estimating to find the digits, one at a time. Suppose 12321 = n ². Since 10 000 < n ² < 40 000, we have 100 < n < 200, so the first digit of n is 1. Thus n = 100 + a, say, where a is (at most) a 2-digit number. ...

... I certainly see the two numbers 1 and 221 in the same position for each scheme. There are probably more. The question wants me to find them all and sum them. Hmm. I could fill in each table completely and just look for matches. That would be one approach that would work – but it doesn’t feel fun. Ca ...
