+( -) is - and + (+) is +.
- (-) is +
So, 7 + (-9) + (-5) + 6 = 7 - 9 - 5 + 6 = 13 - 14 = -1

We know that ( and ) are equicalent to multiplication signs. And +*- = - and -*-=+ and +*+=+
Thus, you can write 7+(-9)+(-5)+6
as 7-9-5+6 ( as +*- = - )
Using BODMAS rule, 7-9-5+6
= 7-9+1 ( because -5+6=+1)
= 7-8 (because -9+1=-8)
= -1
Hence the final answer is -1

Do this the simple way, group all the + # , 7+6=13; then the negative numbers, -9 and -5= -14; now add the two
-14 +13= -1

adding a negative is the same as subtracting so...
7-9-5+6=-1

Okay. Start with 7. Then we add -9( Basically subtract 9 ) and we get -2. then add -5 (subtract 5) and we get -7. Add 6 we got a final answer of -1.

7+(-14)+6= -7
-7+6= -1
