calculator suddenly changes

I was working with the Windows Calculator, scientific mode.

I closed the calc, then when reopened, the scientifc mode changed.

Before I had the roots function on the same "page".
Now there's a new button "2nd" that I have to click to see the roots function.




Same if calc is full-screen.

What happened ?


Can I go back to the previous scientific calc ?



Calculator Version 10.1910.0.0

Just looked at mine and it is the same as yours, don't use the scientific part so not sure what it looked like before. Could it have come with the updates a couple of days ago?
