Unique Features

Reversible Keybord Demonstration Flash
The Reversible Keyboard gives you a 2-in-1 Graphing Calculator. Keys for basic functions are on one side, while keys for advanced functions are on the other. Functions appearing on the menu display differ depending on which side of the keyboard is being used. The Reversible Keyboard saves you from having to get two separate models for different levels.
Basic Keyboard Side
for use at junior high school level
Examples of Functions
• Fraction Study
Includes a function for simplifying fractions. Finds common divisor either automatically or manually, leading to more effective learning.

• Pie Chart
Using a pie chart makes it easy to compare each part to the whole. The data can be displayed either as raw numbers or as percentages of the whole.

• Remainder Calculation
Using the [int÷] key allows the user to calculate quotients and remainders easily.

Advanced Keyboard Side
for use at high school level (includes all the functions of the Basic Keyboard)
Examples of Functions
• Scientific Graphing
Graphs can be drawn in one of 4 modes: by rectangular coordinates, by polar coordinates, by parameters, or by sequences. The Split Screen makes it easy to analyse the relationship between a graph and a table.

• Statistics/Regression
Data can be easily input and revised in tabular form. You can also draw a variety of graphs, such as statistical graphs (9 types) and regression graphs (14 types), which are useful for analysing data.
