wischi, to memes in Good thing I don't know how to read music

True and I obviously have no idea what I’m doing. But I’m sure it doesn’t matter because I don’t know anything about music, don’t have absolute pitch and just pressed e f f on an online midi keyboard 🤣

“die” is probably from a german song. It’s the article for female nouns (or plurals). Couldn’t guess the song though based on those three notes.

The joke is because of “degrees” (also to measure angles) and “radians”

Joules is unfortunately a vector because it’s over a distance in a direction.

What? Joule is an energy unit and energy is a scalar quantity and not a vector. There is no “energy direction” and no “distance”.

Edit: even your edit doesn’t make sense. Provide a source that says that energy or joule is somehow a vector.

“recently”, they are the standard for almost 25 years now.

Just saw the image you posted and it’s awesome :-) I’m part of the group that can’t solve it, because I don’t know the 🌭 function from the top of my head. I also found the choice of symbols interesting that 🌭 is analytical continuation of 🍔 and not the other way round 🤣

Chat GPT’s answer for me:

Certainly! The expression 6/2(1+2) is ambiguous due to the implicit multiplication. Let’s solve it in both ways:

  1. Implicit multiplication with higher priority:

[ \frac{6}{2}(1+2) ]

First, solve the parentheses:

[ \frac{6}{2}(3) ]

Now, perform the division:

[ 3 \times 3 = 9 ]

  1. Implicit multiplication with the same priority as division:

[ \frac{6}{2(1+2)} ]

Again, solve the parentheses:

[ \frac{6}{2(3)} ]

Now, perform the multiplication first:

[ \frac{6}{6} = 1 ]

So, depending on the interpretation of implicit multiplication, you can get different results: 9 or 1.

I think it’s funny that ChatGPT figured out 1 and 9 but has the steps completely backwards. First it points out what has high priority and then does the exact opposite, both times 🤣

Thank you for taking the time reading it.

All calculators that are listed in the article as following weak juxtaposition would interpreted it that way.

You are right the manual isn’t very clear here. My guess is that parentheses are also considered Type B functions. I actually chose those calculators because I have them here and can test things and because they split the implicit multiplication priority. Most other calculators just state “implicit multiplication” and that’s it.

My guess is that the list of Type B functions is not complete but implicit multiplication with parentheses should be considered important enough for it to be documented.

In the blog post there are even more. Texas Instruments, HP and Canon also have calculators, and some of them show 9 and some 1.

Did you read the blog post? I also quoted the exact same thing.

Regarding your first part in general true, but in this case the sheer amount of calculators for both conventions show that this is indeed intended behavior.

Regarding your second point I tried to address that in the “distributive property” section, maybe I need to rewrite it a bit to be more clear.

@Prunebutt meant 4.5! and not 4.5. Because it’s not an integer we have to use the gamma function, the extension of the factorial function to get the actual mean between 1 and 9 => 4.5! = 52.3428 which looks about right 🤣
