c ≠ d
c, d ∈ { 0, 1, 2, ... 9 }

The first equation establishes a straightforward relationship between c and d, but the third one puts this puzzle in the realm of discrete mathematics or number theory. The numerical solvers in calculators aren't designed for such problems

I was hoping that there was a way to insert those somehow as conditions (like inequalities or such things). Thanks!
