### 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.

### 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.
