-4.5 + 4.4 + -6.7 + 6.8

0

Step-by-step explanation:

just because the negative sign is in front, doesn't mean anything. its the same as subtracting. easiest way to do this is to add the positive numbers together first, then subtract the negative.

4.4 & 6.8 are positive and added together, they = 11.2

now subtract 4.5 & 6.7 from 11.2

and your final answer is 0
