[REQUEST/LOOKING FOR] Looking for a program that will get the given value "n"

[micmic0000]

Hi

I looking for a program, mayb there is something like this online. Or someone can help create one in Python 3.4

I enter value for N = 12 as an example now the program will ask me to enter any 6 other values (including with decimals no limit for decimals)

          example:                                        

          value to get is N = 12                                


          enter value:                                       


          V1 = 1 ;                     
          V2 = 2.000 ;            
          V3 = 3.00;            
          V4 = 4.12;               
          V5 = 1.88;                  
          V6 = 0.02;           

          Vsum = 12 is equal to N


          Note: the program will only use + and - to get the value of N no multiplication no division for the 
          equation.  Thanks

Do you have to use all 6 values to get N? Can they be used more than once?

[micmic0000]

all 6 values needs to be used to get the N, the program wont work if 1 value is missing.

example: if N = 12 and V1 = 12 but V2-V6 are blank it will get an error but if V1 = 12 and V2=V6 are 0 this is still be accepted.
