Calculation with the System
Storyboard
In all cases it is necessary to perform calculations. It is usually largely automated so it is enough to select the equation, the variables and the system calculates the new variable. In case you use the calculator without predefined variables you have to be careful to use the calculator correctly.

The following video explains how to find the equations that the case requires:
First show the search for a specific reaction and then where are general forms that include all the equations that the case starts.

Problem of not having calculated a value

The way it is calculated is sequential. That is, there are calculations that must be made before others because the seconds require results from the first.
If you try to perform a calculation before all the previous calculations exist, more than one variable will be assigned that does not yet have values, so the system will not be able to calculate it.
In this situation the system indicates that there are variables that must be calculated previously:
and values will not be stored.

Calculation Confirmation

If the calculation was made correctly, the system indicates it with the message:
This is:
* the equation is correct
* the variables were assigned correctly
* only one variable had not yet been calculated
* all other variables were entered or calculated
