1. Different integers A, B, C, D consist of the same digits. A+B=C. B+C=D. What are the smallest numbers which satisfy this?
2. Can it also be solved if we add C+D=E?
3. What if instead we add A+D=E?
(In reply to re: computer solution - wondering
Now that I read it again, it looks like your interpretation is correct. I'll have to work on that.
Also, even with my previous interpretation I had mistakenly allowed only A < B. It affects the first answer, which should have been
13 9 22 31
but that's rather moot now.
