+/- function on HP-28S??



#5

Hi all,
I just bought an HP-28S without a users manual and am trying to get by without it until I can find one. I'm having a problem finding the +/- function...
example: 2.5E-6 (how do you enter the "-" ??)
Anyone know?
regards,
OrB


#6

Must be a recent HP convert. For ages, negative numbers were entered using the CHS (change sign) key.

Welcome to the way of truth.


#7

It's nice to see so many converting over from the "Dark side" isn't it?

Paul

#8

CHS FOREVER!

tm


#9

123456 to remove

#10

Who would've thought the CHS key could be the one.
I love my HP28S and have a hard time putting it down. Girlfriend's getting a little jealous.....might have to hide the calculator somewhere safe lest it be sacrificied.
thanks all,
OrB
