When subtracting two negative numbers (-2 - -3), do I change it to an addition problem (-2+3)?

On my algebra hw, I was working and on one problem it got down to -2 - -3. Usually I would just subtract 3 from -2, but it just doesn't seem like the right answer...any help?

I thought this unit was incredibly easy last year in 8th grade :)
Also, my teacher showed us a video from teacher tube to help with multiplying and dividing those things.

Basically it said that when you're multiplying or dividing, two negatives make a positive. It was a very catchy video :p.

I thought -2 + -3 = -5. No?
