Ärende: Headache, anybody ?
===========================
Hello Miles.

ah the substitution game.

I'mm assuming also no leading 0s (as is usual)

for TEN-1 to be a multiple of nine, and a square it must be a (multiple of
three) squared


  X     ^2  "TEN"     NINETY

 12^2  144   145       5i541y
 15^x  225   226 bad
 18^2  324   325       5i523y
 21^2  441   442 bad
 24^2  576   577 bad
 27^2  729   730       0i037y bad
 30^2  900   901       1i109y

since NINETY is divsible by 9 that constrains I and Y so there's only
one degree freedom for each case.

  "TEN"   NINETY

   145    505413
   145    515412  bad
   145    525411  bad

   901    171099  bad
   901    181098  bad
   901    191097  bad

so  how much is SIX  - take the bifference between the rouded-down square roots
of both

 "TEN"  NINETY  sqrt( NINETY) - sqrt(TEN)

    ANXIETY
    ?185093

 anxiety is one of 4185093, 6185093, or 7185093.

 Unless there some other restriction you forgot to mention
