2 Essential functions for learning all in one

A wide range of essential functions are effective for education and available to support student's learning.

• Spreadsheet

  Useful for learning statistics.
  Up to 5 columns x 45 rows
  (maximum of 170 data items)

1Essential functions

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.

Sequence: a₁=2 and a_n+1 -2a_n-3 (n=1, 2, 3 ..)

a₁-2, a₂=1, a₃=-1, a₄=-5, a₅=-13

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.

2Variety of functions available to support student's learning.

From basic level to advanced math level for secondary and tertiary education.

• Equation

• Integration

Example

Solve the matrix calculation.

ClassWiz Series

• Able to have the answer in 1 display as textbook form

MS series

• Need 4 displays to enter numbers in Matrix B

• Need 4 displays to check the final answer

3 Simple and quick calculations

Simple key strokes and visualized formulas make calculations faster.
Fast calculation for smooth performance in class or during examinations.

Example

Calculate the mean height of 5 students.

< Students’ height >
176cm, 180cm, 173cm, 180cm, 175cm

ClassWiz series 2 steps

Fewer keystrokes and faster !!

Comment

I love the simplicity of the Casio fx-991EX (ClassWiz). The use of a natural textbook display and high resolution screen allows me to present mathematics the way students see mathematics in their textbooks. The ClassWiz also allows me to teach concepts I never could before. Statistics, data analysis, probability and spreadsheets are all now within the realm of possibility. My favorite feature is the QR Code generator. I now have the power of a graphing calculator in the hands of every student. The ClassWiz allows me to focus on the learning and not the button pushing.

The use of icons on the menu screen improves viewability. Selection of the desired function is quick and easy.

Input and display fractions, powers, logarithms, roots, and other mathematical formulas and symbols just as they appear in textbooks.

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.

Nearly all English words are displayed on the screen in unabbreviated form. Interactive menu display realizes more intuitive operation.

ClassWiz contains calculation functions that support even advanced mathematical operations, including spreadsheet calculations, 4 × 4 matrix calculations, calculation of simultaneous equations with four unknowns and quartic equations, and advanced statistical distribution calculations.
