I'm sorry, but this whole article just feels heavily AI-generated. The telltales are all over the place (the kinds of headline questions, the structure, the way math is presented, the super concise keyword salads, the bolding, the capital letters all over the place, etc.).

Do your own research when reading the information in this article, I wouldn't be surprised if there are hallucinations or incorrect information. FWIW, the author claims to work in this space.
