Question

Let u = <-3,4>, v = <8, 2>. Find u + v.

Answer 1

Answer:   < 5, 6 >

=================================================

Explanation:

In general if

u = < a, b > and v = < c, d >

then,

u+v = < a+c, b+d >

Basically we add the x coordinates separately and the y coordinates are added separately.

----------

So,

u = < -3, 4 >

v = < 8, 2 >

u + v = < -3+8, 4+2 >

u + v = < 5, 6 >
