ChatGPT 4o shows answers in a red codes for a simple maths questions

Last week, I was looking into ChatGPT for reference only but then I encountered some issue where it only shows a red line codes with the solution but it’s quite tricky & tried today and it’s still the same. I thought this issue have been solved but I think it haven’t solved yet. I don’t know whether it’s my mistake or ChatGPT mistake. Please do look into this matter, thank you!

I was wondering the same thing…
