From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]:

Problem  \Prob"lem\,  n.  [F.  probl[`e]me,  L.  problema,  fr  Gr  ?
anything  thrown  forward,  a  question  proposed  for  solution,
fr  ?  to  throw  or  lay  before  ?  before  forward  +  ?  to  throw.
Cf  {Parable}.  ]
1.  A  question  proposed  for  solution;  a  matter  stated  for
examination  or  proof;  hence  a  matter  difficult  of
solution  or  settlement;  a  doubtful  case;  a  question
involving  doubt.  --Bacon.

2.  (Math.)  Anything  which  is  required  to  be  done  as  in
geometry,  to  bisect  a  line  to  draw  a  perpendicular;  or
in  algebra,  to  find  an  unknown  quantity.

Note:  Problem  differs  from  theorem  in  this  that  a  problem  is
something  to  be  done  as  to  bisect  a  triangle,  to
describe  a  circle,  etc.;  a  theorem  is  something  to  be
proved,  as  that  all  the  angles  of  a  triangle  are  equal
to  two  right  angles.

{Plane  problem}  (Geom.),  a  problem  that  can  be  solved  by  the
use  of  the  rule  and  compass.

{Solid  problem}  (Geom.),  a  problem  requiring  in  its  geometric
solution  the  use  of  a  conic  section  or  higher  curve.
