Adding and Subtracting Vectors
In linear algebra, the sum A+B of two vectors (A and B) is equivalent to the sum of the corresponding components of A and B. For instance, if Vector A is {1, 3, 4}
and Vector B is {2, 5, 9}
, the sum A+B is {1+2, 3+5, 4+9} = {3, 8, 13}
.
Similarly, the difference A-B between two vectors (again, A and B) is equal to the difference between the corresponding components of A and B. The difference A-B with the above vectors is {1-2, 3-5, 4-9} = {-1, -2, -5}
.
