Ma Error/nonreal answer
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 about 999!
Or even 99! that's three.
Or just hit the ln button, instant error!

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

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?
Don't pay attention to this signature, it's contradictory.

writing haskell makes your life easier:

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

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 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 (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],[=].

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..........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...

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

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.
