wischi, to memes in 6÷2(1+2)

Thank you for taking the time to read it.

Sure. In a few weeks there will be another article about a new battery that “scientist found” with 100 times the capacity of modern Li-Ion batteries 🤣

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 🤣

“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 🤣

Same priority operations are solved from left to right. There is not a single credible calculator that would evaluate “6 / 2 * 3” to anything else but 9.

But I challenge you to show me a calculator that says otherwise. In the blog are about 2 or 3 dozend calculators referenced by name all of them say the same thing. Instead of a calculator you can also name a single expert in the field who would say that 6 / 2 * 3 is anything but 9.
