Take note:  
i) Negative +  Negative =  -(Add the two numbers)
Example:  
 -10 + -3  =  - (10+3)
               = -13.
Therefore:    -8 + -3 = -11.  ( Just add the two numbers and put the minus sign).

ii) Small number - Big number = - (big number - small number).
Example:
3 - 5    =   - (5-3)
          = -2.  (just subtract the small number from the big number and add the minus sign)

Example:  1 -7 = -6.  Using same logic.
