If you mean when you subtract a negative from a positive what does it make? If so, you will get a positive answer. This is because the two negative symbols are basically multiplied, and if you multiply two negatives you get a positive, so a positive number minus a negative number becomes a positive number plus a positive number.
6 - (-5) = 11
2 - (-10) = 12

To subtract a negative number is equivalent to adding a positive number. Two negatives multiplied make a positive.
When subtracting negative integers, one can relate it to the overall attitude of a room. If a room contains a number of people of positive and negative attitude you can get rid of people (or subtract people) with negative attitudes to make the overall attitude of the room more positive. If you subtract a negative integer it makes it positive.
You will get a positive integer. If you subtract a negative number, you will be adding it. I think of it like 2 minuses equals a plus. :P
-- Remember which one was positive and which was negative, then forget about the signs.-- Write down the one that was positive-- Subtract from it the one that was negative(Notice that if the negative one was bigger, then the answer will be negative.)
a negative minus a negative = a positive. the two negatives put together make a plus sign. example... 5-(-7) = 13
