Question about Casio FX-300MS Calculator
There is nothing special for the natural logarithm: you use the [LN] key.
You press [LN] , enter the number, then hit [=].
Here you have a negative 100, you must use the change sign (-)
[(-)] 100 [+] 88[*] [LN] 80 [=] The result is 285.6183439
Hope it helps.
