-3 + -5 + 1

Consider that "+ -" is just another way of saying "minus" or " - " (I actually do this all the time personally. Makes it easier to understand numbers as negatives and not negative as a function).

So we have:

- 3 - 5 + 1

Combine the negatives together:

- 8 + 1

Now combine these two together:

 -7
