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

Example:
A = 4.25 +
3.16*i, B = -2.27 + 1.04*i
Option 0
(+): 1.98 + 4.20*i
Option 1
(*): -12.93 – 2.75*i
Option 2 (÷):
-1.02 – 1.86*i
