I wrote a (very long) blog post about those viral math problems and am looking for feedback, especially from people who are not convinced that the problem is ambiguous.

It’s about a 30min read so thank you in advance if you really take the time to read it, but I think it’s worth it if you joined such discussions in the past, but I’m probably biased because I wrote it :)

    You guys are doing it all wrong: ask chatgpt for the correct answer and paste it here. Done.

    Who needs to learn or know anything really?

      ChatGPT’s Answer:

      The expression 6/2(1+2) involves both multiplication and division. According to the order of operations (PEMDAS/BODMAS), you should perform operations inside parentheses first, then any multiplication or division from left to right.

      Let’s break down the expression step by step:

      Inside the parentheses: 1 + 2 = 3

      Now the expression becomes 6/2 * 3

      Division: 6/2 = 3

      Multiplication: 3 * 3 = 9

      So, 6/2(1+2) is equal to 9.

        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 🤣
