Working with variables

You can store values using variable_name := value or the other way around value =: variable_name.
All defined variables are available across pages within the same problem. This allows for building dynamic, interconnected content. Sliders, table columns and graph functions are stored automatically.
To remove a variable, use the DelVar command. Alternatively, you can insert a new problem to clear all previous variables.
