You can switch the display mode for complex numbers by pressing SHIFT MODE down 3 and picking one. This will display the current result in the selected mode.

You can also override the current display mode and specify the format. Add these keystrokes at the end of a calculation: SHIFT 2 then 3 for polar or 4 for rectangular.

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

At first, **Rect** and **Polar** are a display-format instructions, not a conversion functions. Polar instruction displays complex value in rectangular form **a + bi**. The complex value can have any complex form. __However, an__** r*exp(i*theta)** causes an eror in Degree angle mode according to the TI avowal. See captured images below

Conversion of polar form to rectangular:

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in polar form, e.g. r = 3, θ = 42Ā°: 3 [SHFT] [(-)] 42 [=]
- Switch to rectangular view: [SHFT] [2] [4]

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in rectangular form, e.g. real part = 2, imag part = 3: 2 [+] 5 [ENG] [=]
- Switch to polar view: [SHFT] [2] [3]
