47.932 + 56 + 97.168 - 67 - 78.3 - 22.7
(47.932 + 56 + 97.168) - (67 + 78.3 + 22.7)
i.e. 201.1 - 168.0
33.10

 Keep all +ve sign digits all together, and -ve all together

  i.e (59.67 + 61.73 + 5.89 + 0.093) - 42.83

        127.383 - 42.83

        84.553 (Ans)

        Adding all:- 

        59.670
        61.730
        05.890
        00.093
     ------------
       127.383
     ------------
   

 Adding all:- 

                   
        05.838
        06.929
        07.001

        39.655
     ------------
   

 On adding the following :-
 
  4789300 x 10 = 47893000

  4789300 x 1  =  4789300

  --------------------------------
               =  52682300                 
  --------------------------------
  
  

On adding the following:- 

  458963 x 10 = 4589630

  458963 x  2 =  917926

  --------------------------------
               =  5507556                 
  --------------------------------
  
  

On adding the following:- 

  444258 x 10 = 4442580

  444258 x  5 = 2221290

  --------------------------------
               =  6663870                 
  --------------------------------
  
  

On Substracting 2nd from 1st:- 

  1258634 x 10 = 12586340   ---------------1st

  1258634 x  1 =  1258634   ---------------2nd

  --------------------------------
               = 11327706                 
  --------------------------------
  
  

First keep the dot below one another and then adding all:- 

  0.8239    
  0.7620
  0.0200   
  5.2600                    
  --------
  6.8959                     
  --------
  
  

First keep the digits one side (Left) while alphabet (p) on another side (Right) :-
 
  (Change the sign +/-, on moving the digits or alphabet)

  15.9273 - 11.0049 = p

  i.e.  p = 15.9273 - 11.0049


  Now subtract the 2nd from 1st

  15.9273 ----------- 1st   
  11.0049 ----------- 2nd
  --------
  4.9224                     
  --------
  
  

First keep the digits one side (Left) while alphabet (q) on another side (Right) :-
 
  (Change the sign +/-, on moving the digits or alphabet)

  172.23 - 63.83 - 22 = q 

  i.e.  q = 172.23 - 63.83 - 22

        q = 172.23 - (63.83 + 22.00)

        q = 172.23 - 85.83

        q = 86.40
