-5 + 6 = 1
Add negative eleven to negative four and one third to obtain negative fifteen and one third: (-11) + (-4 1/3) = -15 1/3
-2x+3+1=-7 -2x=-11 x=11/2
x = -2.5
negative one and a half
0, of course! 4+-4=4-4. One negative plus one positive equals one negative.

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.
