When you enter or edit a value for a variable in the
interactive solver editor, the new value is stored in
memory to that variable.
You can enter an expression for a variable value. It is
evaluated when you move to the next variable.
Expressions must resolve to real numbers at each step
during the iteration.
You can store equations to any
