(-2) - (-7) = 5

Think of it as you having a 2$ debt, then you get rid of a 7$ debt. Sorry for bad english, btw why don't you just use the calculator for that problem?

To add on to Cavallin ^^^

 

Theres also this thing called the double negative rule where if you have 

 

(-2) - (-7)                If you take away the parenthesis you see two negative symbols right next to each other

 

If ever you see that    -2 - -7         the double negative turns into a positive so your new problem would be

 

-2 +7 = 5
