Does addition of two vectors give you scalar of vector quantity?

Answer 1

Vectors have the magnitude and direction, scalars have only magnitude. Addition of vectors A and B will produce a vector C. Such that C=A+B. C is a vector because it will have magnitude and the direction.
For an example consider a moving sidewalk such as those in the airports. If such a sidewalk is moving South at 2 miles per hour, its velocity is vector A. If a person walking on that sidewalk at 3 miles per hour also South, that persons velocity is vector B. However, that person will be moving at 2+3=5 miles per hour in relation to a stationary observer or in other words with the velocity of vector C.
Further, consider A+B1=C1.
If that person is walking North, or the opposite direction of treadmill's (if he or she got on the wrong sidewalk :) ), that person's velocity will be -3 miles per hour that will be vector B1. Thus in relation to a stationary observer that person is moving 2+(-3)=(-1) miles per hour towards South, the velocity of vector C1. That is the person is moving North at 1 mile per hour.

Answer 2

Adding two vectors typically results in another vector quantity, not a scalar. The resultant vector is found using vector addition, which considers both the magnitude and direction of the original vectors.
