phi · Answer

I would go in order
first
6 + -18   
they are different signs.  so first subtract the smaller from the bigger:  18-6=12
then assign the sign of the "bigger" number.  18 is really -18  so the answer is -12

now your problem is 
-12 + -13 + 9

can you continue?  what is -12 + -13 ?
