ACT Math
Lesson Plan
Arithmetic with complex numbers
Goals / Objectives
Add, subtract and multiply complex numbers, reducing i^2 to -1 and writing every result in standard form a + bi
Add and subtract complex numbers by combining real parts and imaginary parts separately
Multiply a complex number by a single factor or by a second complex binomial, squaring a binomial by expanding it as a product
Compute (a+bi)(a-bi) and state why the result is real
Explain why the like-terms analogy holds for complex addition but fails for complex multiplication
Standards
