multiply everything by -1 to get

-6+(-13)=?

multiply by -1

6+13=?

that's easy to figure out

6+13=19

now multiply by -1 again to put it back how it was

-6+(-13)=-19

The reason is this: you are missing 6 items. You lose 13 more items. How many are you missing now? Now you're missing 19 items.
