Miscellaneous  Multiplication

        Here  I tell  you some  miscellaneous  methods of multiplication from  18 to 101
        These methods are based on presence of mind. As you know multiplication/division of 2, 5 ,9,10,11, 25,50, is very
        easy in comparison of other numbers . So we use these multiplications /divisions  in these methods
 

        18 x296   =( 20-2 )x296  =5920-592=5328

        19x296  = ( 20-1 )x296  =5920-296=5328

        21x296  = ( 20+1 )x296  =5920+296=6216

        22 x296   =( 20+2 )x296  =5920+592=6512     or   11x2x296

        23x296  = ( 2x22+1 )x296  =6212+296=6808   or   29600/4-2x296 =7400-592=6808

        24x296  = ( 100/4-1 )x296  =7400-296=7104

       25x296  = ( 100/4 )x296  =7400

       26x296  = ( 100/4+1 )x296  =7400+296=7696

       27x296  = ( 30-3 )x296  =8880-888=7992

       28x296  = ( 30-2 )x296  =8880-592=8288

       29x296  = ( 30-1 )x296  =8880-296=8584

       31x804  = (30+1)x804 =24120+804=24924 

       32x804  = (30+2)x804 =24120+1604=25728

       33x804  = (30+3)x804 =24120+2412=26532     or  3x11x804

       34x804  =(3x11+1)x804 =27336

       35x804  =(25+10)x804 =(100/4 +10)x804      or 70/2 x804

       36x804 =(3x11+3)x804    or ( 4x10-4)x804

       37 x..... =(40-3) x......

      38x.....  =(40-2)x.......

      39x....=(40-1)x.....

      41x....=(40+1)x....

      42x.... (40+2)x....

      43x...=(40+3)x....

      44x....=(4x11)x....or  (40 +4)

     45x..... = 90/2

     46x....  =(90/2+1)x...

     47x..... =(90/2+2)x...

    48x..... =(100/2-2)x....

    49x.....=(100/2-1)x....

    50x.....=100/2x....

   51x.....=(100/2+1)x.....

   52x...  =(100/2+2)x

   53x....= (110/2 -2)x

   54x....= (110/2+1)x

  55x ..  = ( 110/ 2  )x...

  56 x.. = ( 110./2+1 )x...

  57 x.. = (  60-3 )x..or(2x3x10-3)

  58x....= (60-2 )x....

 59x... = ( 60-1 )x...

 61x..  = (60+1 )x...

 62x... = ( 60+2)x

 63x    = ( 70-7 )x.....

64x... = (  130/2-1 )x...  

65x    = ( 10+11x10/2)x...

66x    = ( 2x3x11 )x

67x     = ( 2x3x11+1 )x

68x    = ( 70-2)x   or  (101 -3x11)  Multiply of 101 is like 100  if there is only two digit repeat two time same number
                                                      36x101 =3636    if three digit  333x101=   33 (3+3)33=33633

69x    = (70-1)x

71x    =(  70+1)x

72x   = ( 80-8)x        or( 300/4  -3)x       or (6x11+6)x

73x  = (300/4-2)x

74x  =  (300/4-1)x

75x =  300/4

76x =( 300/4+1)x

77x  =7x11x

78x  =(80-2) x  or( 100-2x11)x

79x  =(80-1)x   or ( 101 -2x11)

81 x = (80+1)x     or 9x9

82x  =(80+2 )x

83x  =(80+3)x

84x   =(77+7)x

85x   = (300/4+10)x

86x =  ( 8x11-2)x

87x  = (8x11-1)x

88x=  8x11x

89x=(90-1)x or  ( 100-11)x

90x =9x10x or( 100-10 )x

91x  = ( 101-10)x  or ( 90+1)x

92x  =(90+2)x   or (100-8)x

93x= (90+3)x    or (100-7)

94x=(100-6)x

95x=( 100 -10/2)x

96x=(100-4)x

97x=(100-3)x

98x=(100-2)x

99x=(100-1)x

101=(100+1)x
