  15 2 Fundamental Operation  This section covers the various modes available with the computer using a series of simple examples. These procedures should be mastered before attempting more complex operations.  2.1 CAL Mode The CAL mode is in effect each time the power of the unit is switched ON. Arithmetic calculations, function calculations, formula storage calculations, program execution can be performed in this mode.  EXAMPLE: 2.5+3.5-2=  OPERATION: 2   .   5  +  3   .   5   -   2 . . 3.5+3.5–2  4...
