The isExpanded method checks that an expression is in its most expanded form.

isExpanded doesn’t take any value and is generally used as a supporting method in conjunction with equivSymbolic.

Additional Options

  • Allow thousands separator
    Authors can specify what separators can be used by the student. From the Thousand Separator drop-down menu, you can select dot, comma, and/or space. The Decimal Separator menu contains the option for either a dot or a comma. Note that the specified thousand separators and decimal separator cannot be the same, e.g. both dot.
  • Inverse result
    Enabling this means that the value specified in the Value field will not be accepted as the correct answer. It is a useful way of excluding very specific answers from validation.
