What kind of calculation do you use ?When you want to get the log value of a number , enter the value , then press log It is similar to finding the trigonometry values of an angle For example sin 50 degree , press 50 then the sin symbol

(In fx 50 F, mode 4 is in degree and mode 5 in radian . used in A Maths only)If it is fx 50F, press 3, log , 除, 2, log , then you will get the answer I think the mechanism of other calculators are similar too
