Question

Suppose you want to subtract: -4-(-2)

Answer 1

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:

`-4-(-2)`

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
