what is the least number of button presses you can do on your calculator so as to get a Mathematical Error. On mine it is 4 (including equals), unless of course I turn it on a+bi mode.

You can do that on all calculators with 4 buttons...
how boring, should I delete this thread?
No....was it a trick question....or did you think that there was a better solution...
I was bored.
How about 999!
Or even 99! that's three.
Or just hit the ln button, instant error!
You have to include the = button so that is 4...;)Quote:

On my calc, you have to press 4 buttons to get that ! sign. So that meens that that opereration would take 7...:DQuote:

If you hit the ln button you will have a syntax error, not a Mathematocal error....;)
shift -> paste -> enter
/ -> enter (syntax error)
give it to your friend, let him set it up, you press enter (one button)
oh, did I cheat?
hehe, I never thought of that.
note: log 0 is not syntax error its not defined.
Was that one for me....he didn't say ln 0 he said just ln...;)....and that is syntax error....;)Quote:

well depends on the machine, some evaluates ln postfixwise, and then it would be a not defined error ;)
even if it is post fix...it still is a "function" and needs a parameter...as long as it doesn't get that parameter it will result in a syntax error.....;)
nope, post fix operations are done on whats on the display, and when you start the machine you see 0 ;)

On my calculator, you don't have to press =, that'd be redundent.
Listen to kedaman.Quote:

I have never used a calculator that has a ln function that starts with showing 0 first without any button presses (except software calculators)Quote:

they don't "start with" thats the point with prefix operators, postfix operators is something you do on somehting you already have ;)
So that meens that you have to press some other buttons first....;)....and that was the point here...YOU DON'T......Point taken...I win....:D
no you don't ;) most calculators display a 0 at start and you can operate on it directly like typing +1 and get 1.. so I win ;)
hehe, and I thought this would be a boring thread.

None of the advanced calculators I have has that 0 at first. Not my HP postfix calculator, or my Texas or my Casio calculator.....;).....only the old once that I had earlier, but NON of them has the ln function....only normal + - * / sqr() and so on....
with note around things can hardly be boring, no matter what you come up with..
note: well i'm not trying to convince you about something, so either you go buy a normal calculator or just accept the fact that you haven't seen one and therefore can't argue on this.. most people here I think have used a normal calculator where a 0 pops up when you start it.
I suppose you could make a calc. using VB or something that pops up with an Ma Error as the application loads. Zero presses.

I am not buiing it....but I have a new theory....;)....I found my sisters old one line Casio calculator. You know those scientific calcs that they used to use before those with graphs came....that one starts with a 0. But it is not a postfix calc so you can't do it there either....
But can any of you conferm that all one line calcs starts with a zero, and non multi line cals doo.....or is it just a coincident that I have 3 multiline calcs that don't start with a zero....???
And thanks Keda and Acidic that you found me and my incredible boring discussions on lame topics.....I am just buildt that way....:D...I just find it intresting to discuss everything.....but remember I am never getting mad at anyone....;)
I have used hundreds of calculators, most of them nonmultiline, and they do start with 0, the multiline calculators can't start with 0 because you type out the expression explicitely, but thats another story.. yeah note you have to be the only person i know who can go to this length with things, its just incredible.. ;) btw i love picking at you because you don't get mad at me and that is probably what everyone loves about you :D (of course no offense ever is meant, i hate offending people so i only pick on people i know)
Out of all the single line calcs I have used, they all show a zero when you switch them on. So abvious if I press [+],[1] it returns 1. But none of the have a ln button. So I can never try just pressing [ln],[=].
use a functional calculator, they are single line and have ln

Yeah but they are old...like you....I that are so young have never seen an advanced calculator with only one line.....:D.....so new mulitline advanced calculators do not show the 0 at the beginning....:D...end of storry....
haha, they'll never get old as long as the multiline ones run off batteries, I got myself running of solar panels.. and btw you are not allowed to use programmable calculators on the exams... and yeah I've never owned a single line calculator for any other reason, so there you go ;)
I once picked a single line calculator out and attached it to a solar panle too....made the whole calc in a CD-jewel case....:D......we are not allowed to use programmable calculators on exams either....but there has never been anyone checking that we havn't used it on exams either.....but it is just to lame to cheat on exams with programming it.....I wouldn't feel good if I did....I want to earn the grades I get....and everyone in my class, and everyone I know feel the same way here at Engineering school....so cheating is not an option here...
hehe.. I've never seen anyone checking here either, but I didn't want to get caught having one either, so I remember before I got myself a single line calculator I did the calculations on paper on the statistics course exam.. that was a waste of time ;)
Hehe...yeah that I belive....on out statistic exam there was a question where the number was to big to calculate on the calculatopr...something like
(70!+1)/(13!)
...:D
hehe omg.. you should see how fast your av is movinhg his head.. I've almost forgot about it. I know if you calculate combinations or permutations you shouldn't use the factorial because then you get gigantic numbers.. but how come you got that enormous number
My statestic teacher was a professor in Math. So he never used calculators....so in the solution he has onlu used pen and paper....so he didn't know that it was to big for our calculators....:D
For a calc that starts with zero, try the Windows calculator :)
Using it, just press the log button when you start. No equals needed (and it's not a syntax error either). I win :lol:
I'm guessing you start with a 0, right?
Whats wrong with:
[ / ] [ 0 ] [ = ] ?? Thats only 3 buttons... or even:
[ ^ ] [ 0 ] [ = ] ?? Also three, and *should* throw error
Maybe we should be limited to using the Windows calculator so we won't debate about the zeros

One button on my HP48GX. Almost any arithmetic operation will fail if there are no operands. If I turn the calculator on and push the plus button, I get an error.
I can push 0 and the reciprocal button to get an infinite result error (2 buttons). Most HP calculators use a stack. There is no key with the equals function of algebraic calculators.
