Perform the indicated operations for the resulting complex numbers if the given changes are made in the indicated examples of this section.

In Example 3, change the sign of the imaginary part of the second complex number and do the subtraction graphically.

Data from Example 3

Subtract 4 − 2j from 2 − 3 j graphically. Subtracting 4 − 2j is equivalent to adding −4 + 2j. Therefore, we complete the solution by adding −4 + 2j and 2 − 3j, as shown in Fig. 12.7. The result is −2 − j.
