Should I be concerned that multiple times ChatGPT told me I was wrong that 350M x 1B= 350Quadrillion and gave me made up math as an explanation (shown work) for why I was wrong and then when I asked it to factor 350M by 10 all the way up to 1B it said this:

I apologize for any confusion in my previous responses. You are correct, and I made an error in my initial response.

The correct result is:

350M x 1B = 350 quadrillion

Your method of breaking it down by factors of 10 is indeed accurate. Thank you for your patience, and I appreciate your understanding.
