  Multiplication  \Mul`ti*pli*ca"tion\,  n.  [L.  multiplicatio:  cf 
  F.  multiplication.  See  {Multiply}.] 
  1.  The  act  or  process  of  multiplying,  or  of  increasing  in 
  number;  the  state  of  being  multiplied;  as  the 
  multiplication  of  the  human  species  by  natural  generation. 
  The  increase  and  multiplication  of  the  world. 
  2.  (Math.)  The  process  of  repeating,  or  adding  to  itself  any 
  given  number  or  quantity  a  certain  number  of  times; 
  commonly,  the  process  of  ascertaining  by  a  briefer 
  computation  the  result  of  such  repeated  additions;  also 
  the  rule  by  which  the  operation  is  performed;  --  the 
  reverse  of  division. 
  Note:  The  word  multiplication  is  sometimes  used  in 
  mathematics,  particularly  in  multiple  algebra,  to 
  denote  any  distributive  operation  expressed  by  one 
  symbol  upon  any  quantity  or  any  thing  expressed  by 
  another  symbol.  Corresponding  extensions  of  meaning  are 
  given  to  the  words  multiply,  multiplier,  multiplicand, 
  and  product.  Thus  since  [phi](x  +  y)  =  [phi]x  +  [phi]y 
  (see  under  {Distributive}),  where  [phi](x  +  y),  [phi]x, 
  and  [phi]y  indicate  the  results  of  any  distributive 
  operation  represented  by  the  symbol  [phi]  upon  x  +  y, 
  x,  and  y,  severally,  then  because  of  many  very  useful 
  analogies  [phi](x  +  y)  is  called  the  product  of  [phi] 
  and  x  +  y,  and  the  operation  indicated  by  [phi]  is 
  called  multiplication.  Cf  {Facient},  n.,  2. 
  3.  (Bot.)  An  increase  above  the  normal  number  of  parts 
  especially  of  petals;  augmentation. 
  4.  The  art  of  increasing  gold  or  silver  by  magic,  -- 
  attributed  formerly  to  the  alchemists.  [Obs.]  --Chaucer. 
  {Multiplication  table},  a  table  giving  the  product  of  a  set 
  of  numbers  multiplied  in  some  regular  way  commonly,  a 
  table  giving  the  products  of  the  first  ten  or  twelve 
  numbers  multiplied  successively  by  1,  2,  3,  etc.,  up  to  10 
  or  12.
