Hi Erin;
Adding a negative number is the same thing as subtracting.
2+-3
2-3=-1

Comments

Just to add a little here Erin...Any time you see two signs right together as in this problem you do the following:
 
If they are different like +- or -+ or +(-) or -(+) then get rid of the + sign and just make it -.
 
If they are the same like ++ or -- or +(+) or -(-) then it should be just +.
 
This always works!
