You can type in any problem, from a simple operations to complex expressions.
After the problem is entered, the software will start guiding you step by step on how to solve it.

During the solution process, the software displays different popups with tips and explanations of what should be done next and why.
For example, when solving the stage 83+4*72, the software will first display an explanation popup saying that the multiplication operation should be solved now instead of the addition because it has a higher priority.
The operation in the panel for which the explanation is displayed is emphasized by a yellow background and a frame.

Problems are being solved in stages and displayed in the panel one below the other, just like a notebook. Once solved (and during the solution) you can scroll through to review all the problem stages.

Operations are being solved in a separate panel which is opened at the bottom of the screen.
Operations can be solved by using the columns method and keying in a digit after digit as shown below, or by entering the whole result at once as shown in the next image.

By pressing the "Immediate Result" tab on the left side of the panel (pointed by the arrow), the panel display changes so that we can enter the whole result at once.

Explanation popups are being displayed when we solve operations at the "Operation Panel", they explain what should be done now and why in order to calculate the next digit to be entered.

There are operations that can be solved in more than one way.
For those operations, the software will display a popup where you can select the way you want to work with, which is usually the way you work with at class, and the software will remember this selection and continue on.
You can always change the selection later in the menu.

The software can give you problems to practice with.
Each time you click the "Get a Problem" button at the top left side of the screen, a new problem will be given and displayed in the panel.
You can also tell the software to give you problems only in certain areas that you want to practice on, this is done by pressing the "Settings" button underneath the "Get a Problem" button.

The software does not solve the problems by itself, it guides but it is you who solves the problem and the software helps you when you are stuck.
Whenever you enter an incorrect answer, a "Need Help?" bubble is displayed (see below). By pressing it a window will appear with help on how to continue.
