If two negaitve signs occur next to each other in an equation, as in 4 -(-2) then the two negatives becomes a positive and you add the two to get 6. Otherwise, you just do what the equation states:
-5 + 3 you add; =-2.
-5 - 3 you subtract; = -8

When you have a negative and positive in math does it become a negative?
It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.
