Algebra 2 - Using distributive property to help us subtract two complex numbers, (-3+2i) - (4-3i)

The video addresses a common misconception where students confuse subtraction with multiplication in complex numbers. It explains how to rewrite subtraction as an addition problem by negating the subtracted values. The teacher demonstrates combining real and imaginary parts of complex numbers, emphasizing the standard form A + BI.
