-Standards-based and science-based. Standard type with your fingers enough to operate the button, the number of large and clear and be able to meet your basic computing, the standard model to support 12-digit display, enough can use the finger button, arithmetic operations, square root. Science-based with all general functions, all functions are located in the keyboard line in you can not through the menu list to use them. Science-based support figure 24 shows in support of computing preferred mode, hexadecimal conversion function, the standard math function, percentage terms, the square-root function of the calculation and so on.
