I got downvotes for not showing the calculation, fair enough, my mistake. I understand the frustration there. And yeah, you've got to check ChatGPT's work and ask for clarification to understand what it did and why.

That said, I disagree with the assertions made in your post. ChatGPT is a great tool for saving time in doing simple research and calculations, as long as you double check it. It wasn't a year ago, but it is now.

I know, I'm scared by it, too!
