Well you have to rewrite it as -3 + 2
When your subtracting you have to add a line change the sign.
What that phrase means "you add a line" to this minus sign - which turns it into a plus sign +
Then, "change the sign" part means you change the second number in the problem (-2) which is a negative number into a positive number -2 turn it to +2 or if it was +2 turn it to -2
So what you have now is -3 + 2 if you still don't understand the answer don't worry just switch the places around: 2 + -3 or 2-3
The answer is -1

Position yourself on a number line at -3. Then, since you are subtracting, you should face the left. Since you are going -2, you go backwards from the way you are facing 2...
<------ (-3) ------ (-2) ------ (-1) --------------->
You should end up at -1.

since -3-(-2), the two negatives become a positive so it's realy -3+2 which equals -1
the answer is -1
