  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. ]
     [1913 Webster]
     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.
        [1913 Webster]
     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.
        [1913 Webster]
     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.
           [1913 Webster]
     Plane problem (Geom.), a problem that can be solved by the

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