Taking adjacent tags, we look at which letters are shared in the same position, with any hyphens removed. The shared letters give the answer COMBINATORICS. (Which is also a tag in of itself: )

• Given the nature of the puzzle, I think the answer should be ,E28i4@>3:?2E@C:4D. (ROT 47) , right? – noneuclideanisms May 30 '18 at 23:34

An ironic answer given the last tag and open to critique:

combinatoires

which pairs with the tag combinations by,

construction = co
computer-puzzle = om
number-theory = mb
tribnd = bi
weighing = in
pattern = na
calculation-puzzle = at
no-computers = to
algorithm = oi
limerick = ir
rubiks-cube = re
english

Supplement:

combinatories (rare) fits by the same method but combinatorics needs instead of .

• On the right track, but unfortunately incorrect. – noedne May 30 '18 at 16:51
• Thanks @noedne - when I can't solve a puzzle sometimes I feel like asking for the question to be altered! – Tom May 30 '18 at 16:58
