USE YOUR CALCULATOR TO DETERMINE: (http://www.voidware.com/calcs/fx991es.htm, downloaded 26 January 2011)
"I have just discovered a problem with this calculator. There is no keyboard buffering. when entering a long formula, the calculator redraws after each key press, but as the formula becomes longer and slower redraw, it can miss keystrokes. this is especially apparent when entering numbers with repeated digits, like 100 or 4405. these can come out incorrectly as 10 and 405."
Try this:
1÷298.257-0.7292115x10-4 ² × 6378.137³ ÷ 2 ÷ 398600.4405. actual answer is 1.6221172263x10-3
but you will find the last number might come out as 39860.405 (don't forget the x² and x³ terms).
(MY ANSWER: 0.003352813)
WHICH IS THE SAME AS DOING ONLY 1÷298.257 !!!!!!
