I'm pretty sure that -ve plus -ve equals another -ve. -ve plus +ve equals either one of the two, depending on which # is bigger. Same with +ve plus -ve. +ve plus +ve equals +ve. I have done my research and I found out negative plus negative can be negative or positive depending on the bigger number. But, a lot of people make the mistake of subtracting even though the sign is a plus. Example: -7.29 + -3.8= -11.09 but if it was 7.29 + -3.8 the answer 11.09 would be positive because the bigger number is positive.
