The minus is always centered while the negative is always at the top.

If you're in algebraic mode, press 1 - 2

You should see the centered minus sign between the one and the two. Now press ENTER, and you should see the top negative preceding a one.

The two are two different things. The first indicates subtracting one number from another. The second indicates a negative quantity.

Are you sure the minus is at the top? Or was the negative centered?

I'm not sure if it is the only solution, but I had the same problem and I replaced the batteries. My HP35S works fine now.

Previously, however, there was no "battery" annuciator on the screen. This calculator went four years without a bettery change. My HP48GII, on the other hand won't go two months without a change. Go figure.

Given a complex number, ARG (yellow-shift i) will give you the angle in the current angular mode, while ABS (blue-shift +/-) will give you the magnitude.

To extract the real and imaginary components, you'll have to use the relationships

x = r cos(a) and y = r sin(a).
