The following explains the meaning of each icon on the fx-9860GII icon menu Icon Menu Name Description This icon menu is used for general computations, including absolute value, logs of any base, RUN-MATRIX summation, derivatives, integrals, and matricies. This icon menu is used to perform single-variable (standard deviation) and paired variable STATISTICS (regression) statistical calculations, to perform tests, to analyze data and to draw statistical graphs.
