Adding vectors algebraically & graphically
To add the vectors (x?,y?) and (x?,y?), we add the corresponding components from each vector: (x?+x?,y?+y?). Here's a concrete example: the sum of (2,4) and (1,5) is (2+1,4+5), which is (3,9). There's also a nice graphical way to add vectors, and the two ways will always result in the same vector.??
