I just had the following conversation on chatGPT

> Human: what is 36,330 26,951 * (input is expressed in reverse post fix notation)

> chatGPT: To evaluate this expression using reverse Polish notation, we need to use a stack to keep track of the intermediate results. Here's how we can evaluate the expression:

1. Read the first number "36,330" and push it onto the stack. 2. Read the second number "26,951" and push it onto the stack. 3. Read the operator "", pop the top two numbers (26,951 and 36,330) from the stack, multiply them, and push the result (971,914,830) onto the stack. 4. The stack now contains only one number, which is the final result.

Therefore, 36,330 26,951 = 971,914,830 in reverse Polish notation.

I dont think this is about notation.

You should ask it to show its working. The problem is that it uses a fixed amount of thinking for each character - and it writes left to right - while long multiplication is computed right to left. Past a certain number of digits, the amount of "thinking" needed to compute long multiplication in the wrong order (left to right) increases without bound -- accuracy suffers as a result.

A tangential point: Note that multiplication of decimal numbers _has_ to start with the rightmost digit to be done accurately. Consider x = 2/3 + 1/3 = 0.6(6) + 0.3(3), all digits repeating infinitely many times, so there's no rightmost digit: Notice that whichever digit you choose for x before the decimal point (either 0 or 1) could be wrong if you change any digit of 1/3. This is called the Table Maker's Dilemma.

The second paragraph is a tangent. My point was made in the first paragraph.

You said: "I dont think this is about notation" - Why did you ever think it was?

I was thinking along the lines of maybe it reads the digits as individual tokens and reading from left to right it get confused. That's why I thought it might be about notation. I have learned it's definitely not the case (read a bit about what tokens actually mean)

I also tried the show your work methods. I will not paste my conversations here as they are so long but even with showing it's work it doesn't give the right answer. Two funny things I noticed

1. It either uses a completely wrong method to calculate it, or it shows the right "kind" of work and then gets the wrong answer

2. If I tell it it was wrong and it will just agree with me. I multiply two huge numbers and tell it no the answer is actually 42, it will just apologize. Then when I ask the reason why it thinks it's right it will give the most bullshit things lol. Once it even said "I read the number wrong, the second number should be x I read y". The thing is if I had actually given x in the input it would have gotten the answer right.

It's all very confusing.
