Main Application
The Main application is a general-purpose numerical and mathematical calculation application that you can use
to study mathematics and solve mathematical problems. You can use the Main application to perform general
operations from basic arithmetic calculations, to calculations that involve lists, matrices, etc.
Starting up the Main application displays a large white work
area. Use this area for inputting operations and commands.
ClassPad also uses this area to output calculation results.
Basic Main application operations consist of inputting a
calculation expression into the work area and pressing
E. This performs the calculation and then displays its
result on the right side of the work area.

2-1 Basic Calculations
This section explains how to perform basic mathematical operations in the Main application.
Arithmetic Calculations and Parentheses Calculations
You can perform arithmetic calculations by inputting expressions as they are written. The ClassPad
automatically judges the calculation priority sequence for addition, subtraction, multiplication, and division,
functions, and parentheses.
