SOLUTION

To answer this question, let us first understand some rules that guide operations as this:

$\begin{gathered} -*-=+ \\ -*+=- \\ +*+=+ \\ +*-=- \end{gathered}$

So going back to treat this question:

Re-writing this subtraction as an ADDITION of signed numbers, we will have:

$\begin{gathered} -4-(-2) \\ =-4+2 \end{gathered}$

Now to complete this problem the final solution will result in:

$\begin{gathered} =-4+2 \\ =-2 \end{gathered}$

The final answer is -2
