Algebra 2 - Learn how to subtract complex numbers by rewriting as an addition problem, (-7-3i)-(3-i)

The video tutorial explains the concept of subtraction, highlighting its complexity compared to addition. It introduces the technique of rewriting subtraction as an addition problem by negating the subtracted number. The instructor demonstrates this method using examples, emphasizing the ease of making fewer mistakes with addition. The tutorial concludes with grouping and combining real and imaginary numbers to simplify expressions.

Why does the teacher prefer to add rather than subtract?

What is the final result of combining the grouped real and imaginary numbers?
