I need to use the EE button on my BA II plus professional finanacial caluclator. I need to calculate 2.06 * 10^23 divided by 3.78 * 10^28...Help?


If you do not have the Enter Exponent key (EE) you can use the general power key marked [Y^x], the one above the [9] key. Use parentheses to enclose the (10^23) and (10^28).
Frankly, if you have to do many calculations of this kind, better buy yourself a scientific calculator.

Were you also clearing the financial memory with 2nd [CLR TVM], or just the storage memory? If you don't, it's going to keep using whatever value you last used for PMT.

I need to be able to quickly turn a decimal into a fraction using the BA II plus calculator from Texas Instruments


The BA-II Plus is designed for financial applications. It does not do fractions, as do some calculators intended for school use.

Using e on the BA II plus financial calculator


Hello,
To use the exponential function, you must enter the number then press [2nd][e to the x] or [e^x] for short.

e^(-0.1) is entered as (-)0.1 [2nd][e^x], where (-) is the change sign key
You will need to use extra parentheses to avoid errors.

20 - 18*( (-)0.1 [2nd][e^x] ) [=]
The Minus sign between 20 and 18 is the regular one. The (-) before the 0.1 is the change sign key (-) or sometimes labeled +/-. The asterisk is the multiplication sign.
Hope it helps.
