The usage of the conditional system is important when you have too many logical operations. It is really easy to use this feature due to its user-friendly interface.
After choosing Calculator elements created in a calculator, only those elements will be listed in your condition area. Since this feature is dynamic, you cannot put conditions relative to an element that does not exist.
You have to click just once on an element that you need and it will be shown in the working area.
The chosen element has 8 connection points for chaining with other elements. The
icon inside the element is for deleting this element.
To create a connection, you need to drag a line from the selected element to the desired one. The arrow indicates that the right element depends on the left element.
It is possible to create multiple connections and conditions between different elements.
