  Mathematics  \Math`e*mat"ics\,  n.  [F.  math['e]matiques,  pl.,  L. 
  mathematica,  sing.,  Gr  ?  (sc.  ?)  science.  See  {Mathematic}, 
  and  {-ics}.] 
  That  science,  or  class  of  sciences,  which  treats  of  the  exact 
  relations  existing  between  quantities  or  magnitudes,  and  of 
  the  methods  by  which  in  accordance  with  these  relations, 
  quantities  sought  are  deducible  from  other  quantities  known 
  or  supposed;  the  science  of  spatial  and  quantitative 
  relations. 
 
  Note:  Mathematics  embraces  three  departments,  namely:  1. 
  {Arithmetic}.  2.  {Geometry},  including  {Trigonometry} 
  and  {Conic  Sections}.  3.  {Analysis},  in  which  letters 
  are  used  including  {Algebra},  {Analytical  Geometry}, 
  and  {Calculus}.  Each  of  these  divisions  is  divided  into 
  pure  or  abstract,  which  considers  magnitude  or  quantity 
  abstractly,  without  relation  to  matter;  and  mixed  or 
  applied,  which  treats  of  magnitude  as  subsisting  in 
  material  bodies,  and  is  consequently  interwoven  with 
  physical  considerations.
