MATSEC AM Pure Mathematics Complete Prep Course — Lesson 56: Arithmetic of complex numbers

Sarah Mitchell teaches the standard form a plus i b, the single rule that i squared equals minus one, componentwise addition and subtraction, and full bracket expansion for multiplication. She works three plus four i times one minus two i to eleven minus two i, covers equating real and imaginary parts, the four-step cycle of powers of i, and the trap of leaving i inside an imaginary part.
