What is the solution to the expression –2 – 3 – (–4)?

The answer is:  " -1 " . 

Note:

We are given the expresssion:

    →  " - 2  −  3 − (−4) " ;  & are asked to find the solution to this expression;

   →  so we simplify this given expression:


We are only dealing with "subtraction" ; so we go from "left to right", in the order in which they occur; starting with the left.  

{Note that the "parentheses" given in this particular problem does not reflect an operation that we are to perform; so we go with the substraction.}.

  →   " - 2  −  3  =  - 5  "  ;

Then:

   →   " - 5  − (- 4)   =     ?    "  ;   ←  which is our answer to be solved.

Note:


   →   " - 5  − (- 4)   =   - 5 + 4 " ;  

   →   {since a "negative minus a negative is a postive" }.  
  
          →  {that is;  "subtracting a negative" is "adding a positive" .}.


And  we have: 


   →   " - 5  + 4   =  - 1  " .

The answer is:  " -1 " .
