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.
