EEVblog 1479 - Is Your Calculator WRONG?

(1/17) > >>

EEVblog:
Is your calculator WRONG? It could be!
Looking at the issue of implied multiplication and how it can affect your calculations. Why do some Casio and TI calculators give a different result to others? And why do they differ from your phone calculator, google calculator, or Wolfram Alpha?
How Order of Operations matters.

TheSteve:
As someone in the comments mentioned try Hiper Scientific Calculator or Hiper Calc Pro. Then you can pick which you'd prefer :)

It will even give a pop-up the first time you enter the expression asking which you want.

RoGeorge:
The expressions to evaluate shown in the video thumbnail are not the same (pocket calculator screen vs. the Wolfram webpage), notice the extra parentheses in the calculator's LCD.

Thanks Captain Obvious. However if you watched the video for at least a few minutes, you would know why.

Thanks, Captain Smart Ass.  That was feedback for Dave.  The big red "Oops" button suggests there's something wrong with that result, though the thumbnail does not capture any unexpected results, so the thumbnail won't incite one to watch the video.
