**Damon**, Monday, April 6, 2009 at 7:53pmdraw a number line with zero in the middle.

now look at negative(left) + negative(more left) --> more negative

-1 + (-1) = -1-1 = -2

now look at positive + positive

1+1= 2 but you know that

now look at negative + positive

left then right

-1 + 1 = 0

similarly positive + negative

right then left
