Answer 4

To add two numbers with the same sign, poth positive or both negative, drop the signs and add the numbers, then give them the sign they had.
-6.4 + (-3.1)
You are adding two negative numbers, so drop the negatives and add them
6.4 + 3.1 = 9.5
Since both original numbers are negative, the result is negative:
-6.4 + (-3.1) = -9.5
