Changing signs

HP Recommended
HP 10s+

Hi,

 

I'm just wondering what is the simplest way on the calculator to change the sign.  Obviously I can x-1 which changes the sign to a negative or positive figure.  However, I'm used to there being a +/- figure on calculators that I've used in the past.  My calculator does have a (-) button, but I don't seem to be able to use it within other functions.

 

Eg, if I wanted to do 10^-3, how would I do this?  Would I have to do 10 y^x ( 3 x (-) 1).  This seems like a bit of a long winded way of doing the equation, is there an easier way?

 

Thanks,

Tina.

Hi,

 

Use the "(-)"  key before the number you want to be negative, e.g. 10^-3 simply enter: 10^x (-) 3

 

or for 3^-4 enter:  3 y^x (-) 4

 

Regards,

Bart

Hi!, @Tina8:

 

Welcome, to Forum !.

 

For use negative signal, in any calculus, you must write ... (-). It's the unique way.
