@ashfurrow I just checked this and it's true. Brackets change everything.

@adz @ashfurrow It does it without the brackets too! But so does Bing and DuckDuckGo.

@ashfurrow technically the minus sign is a multiplication with -1, therefore it could make sense that it has lower precedence than exponentiation.

Wolfram Alfa gives the same result (even for -3^2), and they are math guys.

@ytg @ashfurrow Precedence rules are PEMDAS:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

So the calculator query shows "-(3 squared)" which is -9.

You have to type "(-3) squared" to get 9.

@cj @ytg it’s really a question of changing language into symbolic math; I think most people would say the answer should be 9, but language is always ambiguous. If I use a calculator and press the buttons “-“, “3”, and “x^2”, the answer is indeed 9.

@ashfurrow @cj @ytg
Not in whatever calculator I appear to have on Ubuntu. pressing '-', '3', and 'x^2' yields -9.

When I use parens around -3, I get 9.

@rcode3 @cj @ytg the iOS calculator app handles this properly, and iirc, my TI-83 did as well.

Again, this is all the ambiguity of language. There's no "correct" answer, but some answers are more correct than others.

@cj @ytg is it a multiplication by -1? I consider “-3” to be its own number unto itself. But again, language :)

@erAck “-3” isn’t an operation, it’s a number. And the ambiguity of the natural speech “negative three squared” is highlighted by the difference of “(negative three) squared” vs “negative (three squared)” - I would argue the first is _more_ correct.

@ashfurrow
The best thing is when you do this to a 13 year old and they give you a look like "ugh, really? I'm too old for your shit"

@tapi @ashfurrow I would argue that the picture gives away too much information on your secret project.

And Dave looks up from YouTube and asks, what kind of containers are you using?

@ashfurrow A transport system for migrants fleeing war torn areas?

@ashfurrow I wonder if the formatting code is converting a number from °F but using the original number for the plural selection.

@ashfurrow I keep thinking that one day we're going to spot buildings that are designed to remind us of legos...

@ashfurrow good morning, please consider living in a drier climate to avoid these issues in the future
