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