What is negative two minus negative three equal?

think of negative numbers as cold numbers and positive numbers as hot numbers.

if you take away cold from a room then the room will get hotter.  so     - - 3 = +3

- 2 - - 3 = -2+3 =1

to get the last bit, start at -2 on the number line and go 3 places in the positive direction.

You end up at 1.
