7 + ( -9) + ( -5) + 6 start with the first two
7 +(-9) is 7 + -9 = -2
-2 + -5 = -7
-7 + 6 = -1

The way to understand it is: when you have a negative and a postive number, subtract the absolute values (the "number without the sign") and keep the sign of the highest number; when you have 2 positives or 2 negatives, you add the absolute values and keep the sign.
So: 7+(-9) = -2
-2 + (-5) = -7
-7 + 6 = -1

=7-9-5+6
7-9=-2
-5+6=1
therefore
7-9-5+6=-2+1= -1

ok let me see if you are asking it right. you want to add positive (+) 7 to a negative (-9) to a negative (-) 5 to a positive (+) 6
ok first you take the 7 and the -9 and you will get a negative (-) 2
then you add the negative (-) 5 and get negative (-) 7
add the positive (+) 6 and you will end with negative (-) 1
negative (-) 1
