Represent the sum of the complex numbers  2−3i and  −1−i on the complex plane.

Use the Point and Segment tools to plot all required points and segments.

 

I'm not good with graphing these stuff. :/

The complex number  2 - 3i  is represented as a dot at the point (2, -3).

Draw this as an arrow with its tail at the origin and its head at (2, -3).

 

The complex number  -1 - i  is represented as a dot at the point (-1, -1).

Draw this as an arrow with its tail at the origin and its head at (-1, -1).

 

The sum of  2 - 3i  and  -1 -i  is  1 - 4i  (which is located at the point (1, -4)).

Show this sum by drawing an arrow from 2 - 3i to 1 - 4i and by drawing another arrow from -1 -i to 1 - 4i.

Represent the final answer by drawing an arrow from the origin to the point (1, -4).
