List display
The new ClassWiz makes it possible to display on the screen twice the number of characters in normal size and six
times the number in small size compared with previous models.
High-resolution LCD drives further evolution!
Higher resolution increases the amount of information that can be displayed and improves usability. In addition,
ClassWiz is equipped with a basic spreadsheet function for creating spreadsheets with up to 5 columns and 45 rows
(maximum of 170 data items).

List display function for thorough, speedy learning
Variables and statistical calculation results stored in memory can be displayed in lists. There's no need to recall and
confirm individual values as with previous models.
High computational competence for performing even advanced mathematics
ClassWiz contains calculation functions that support even advanced mathematical operations, including spreadsheet
calculations, 4 X 4 matrix calculations, calculation of simultaneous equations with four unknowns and quartic
equations, and advanced statistical distribution calculations.
Effective learning for
Advanced Mathematics
Even advanced mathematical calculations are simple to perform and
functions that take advantage of previous unavailable display capabilities
are now possible
Spreadsheet calculations
Statistics
The spreadsheet function can be used for studying statistics which has become important in mathematics classes
Recursion
In addition, the spreadsheet function makes it possible to enter recursive formulas
Riemann Integral
Calculation using advanced Riemann functions is also possible
The spreadsheet function makes it easy to use real-world data even in the classroom, enabling students to effectively
study statistical processing
Advanced statistical distribution calculations
This function makes it possible to perform several different types of distribution calculations such as binomial
probability.
Binomial probability
Matrix calculations
This function makes it possible to perform matrix calculations of up to 4 rows by 4 columns.
4x4 Matrix calculation
Other newly realized calculations
ClassWiz supports other advanced mathematical operations including
Simultaneous linear equations in 2 to 4 unknowns
Second-degree to fourth-degree inequalities
High-degree equations of second to fourth degree
Online Visualization
Service Using QR Code
The input formula and data are converted into a QR Code matching the settings on the calculator, then displayed on
the calculator screen. Display numerical formulas and graphs and use them in study by reading QR Codes with an
application on a smartphone, tablet, or other similar device. (fx-991EX/570EX only)
Convert the numerical formula into a QR Code!
1.Visualization with graphs
Makes formulas visually understandable
2.Easy formula input
Promotes fast, efficient report writing
3.Quick user manual call-up
Makes learning to operate the calculator fast and easy
