HP 12C: Complex Arithmetic (Addition, Multiplication, and Division)

HP 12C:   Complex Arithmetic (Addition, Multiplication, and Division)

Let A and B represent the two complex numbers

A = R1 + R4*i
B = R2 + R5*i

Where i = √-1

Store real components in R1 and R2, and imaginary parts R4 and R5.  Choose the arithmetic calculations:

Enter 0 for addition:  A + B
Enter 1 for multiplication:  A * B
Enter 2 or otherwise for division:  A ÷ B

Result:  C = R3 + R6*i
