Where is my "e" button


If you mean the base of the natural logarithms, there isn't a key to give its value directly. It can be calculated by raising e to the first power by pressing 2nd [e^x] 1 = . [e^x] is on the third key in the leftmost column.

If you mean the exponent of ten, [EE] is the fifth key in the second column.

I cant find my Antilog button on my Casio fx-100MS


The common antilog is the shifted function of the "log" button (marked 10-superscript-x) and the natural antilog is the shifted function of the "ln" button (marked e-superscript-x). The log and ln buttons are both on the third row of the keyboard.

How do i use the LN button


To use Natural Log on the Scientific Texas Instruments, you may need to enter your number first (which is counter-intuitive). E.g. ln 1, press "1" first, and then the LN key.

The button itself is right beside the OFF button. To access the "e to the x" (notice written in yellow just behind it) you would need to hit the 2ND button first.

How do i use the log function on my ba ii Calculator?


To calculate the natural logarithm of the value in the display, just press the LN button. If you need the common (base-10) logarithm, compute it as ln(x)/ln(10). That is, divide the natural logarithm of the value divided by the natural logarithm of ten.
