Yes if you mean like this 4--3. Four MINUS negative 3. Whenever you see two negative signs together, it means you turn the signs into plus, and you are now just adding. Our answer is 7. So in those cases yes, it would always be positive. If you are simply adding two negatives like this -3-4 then it will stay negative. It's like being negative three degrees outside, and getting negative four degrees colder, making it -7 degrees.
