Find the sum of the following vectors: →a = ^i − ^k, →b = 2^j − ^k, →c = 2^i − ^j + 2^k

Add the vectors →a = ^i − ^k, →b = 2^j − ^k and →c = 2^i − ^j + 2^k by writing them in the component form that is →a = <1, 0, −1>, →b = <0, 2, −1> and →c = <2, −1, 2>
The sum of the vectors can be computed as follows:
→a + →b + →c = (1 + 0 + 2, 0 + 2 − 1, −1 − 1 + 2) = <3, 1, 0>
Hence the sum of the vectors is <3, 1, 0>.
