Aplusix Web 

Overview

Aplusix concept

An Aplusix resource proposes exercises.
At launch, the application opens with an exercise statement and the starting expression of the firs exercise.
The user can do her own step from a new empty step or by changing a copy of the starting expression, with the virtual keyboard of Aplusix.
For each action, Aplusix checks the syntax of the expression and the equivalence with the previous step.
Aplusix indicates when the exercise is solved. It also indicates "almost solved" when there are only few simplifications left.

The type of the exercise

Aplusix deals with the following types of exercises:

General settings

When an aplusix web page starts, a general settings panel is visible on the top of the application.
As soon as you click or touch inside to enter something, this panel will be replaced by a virtual keyboard at the bottom of the application. It will appear again if you close the virtual keyboard.
