HHC 2014 HP Trivia question(s) - for those of us who are not there

[Gene]

No response at all? :-(








Ok, try the HP 21 red display LED calculator.

The HP 21 has e^x as a primary key and LN, Log and 10^x as shifted keys.


Also, key 0.5 and press the blue shift key. 0.5 is transformed to the limits of the display setting. Showing essentially "Fix 4" ? Then 0.5 blue shift shows 0.5000 in the display.
