As before,

T=(5, 5)^{T}

There are two ways to form the sum:

T=S + RT=R + S

where

R= ( 4, 3 )^{T}S= ( 1, 2 )^{T}

There are two ways to draw the diagram, depending on which arrow's tail you put at the origin. If you draw both versions, then you get a parallelogram with the sum of the vectors as the diagonal arrow whose tail starts at the origin.

*What is a parallelogram?* you might ask, if your
high school geometry is a bit murky.
A parallelogram is a four sided figure with opposite sides
parallel and equal in length.
So, for example,
the blue arrows representing the vector **s**
are the same length and same direction.
The green arrows representing the vector **r**
have their same length and same direction.

**u** = ( -3, 2 )^{T},
**v** = ( 1, -5 )^{T}
form the sum:
**w** = **u + v**
