The addition of the two hexadecimal numbers in the first equation is straightforward and results in the third hexadecimal number. 
In the second equation, we don't know what A, B, and C represent, but we know they are all some vectors. If they represent positions or displacements, then the addition of two positions or displacements results in another position or displacement. Therefore, C is also a vector.
Since the two given vectors have different values in their third digits, they are certainly not parallel. 
If we assume that the values in the fourth digits have some kind of meaningful representation, like a direction component, then it's possible that the two vectors are perpendicular if the difference in the fourth digits corresponds to a 90-degree angle. However, there's not enough information to confirm this.
