Learn and memorize these simple rules:
1. To multiply the vector ai + bj by the scalar "c", multiply by "c" every component:
c*(ai + bj) = (ac)i + (bc)j.
2. To add the vectors (ai + bj) and (ci + dj) , add coefficients at co-named components:
(ai + bj) and (ci + dj) = (a+c)i + (b+d)j.
Now you know EVERYTHING what you need to do all these assignments on your own.
It is as simple as 2 x 2 = 4.
