The Reversible Keyboard gives you
a 2in1 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. 


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. 



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.
