Try 1 / 2x10^3 to get the wrong answer 500. ( 1 divided by 2000).

Type 1, division function, 2 then the x10 button at the bottom, 3, EXE.

The 991 EX gives the correct answer. So do my HPs ... . This upgrade is complete nonsense.

It may be "by design" but it operates differently than almost any other scientific calculator made in the past 50 years. IMHO This change in operation was unnecessary and foolish.
