Percentages and per mille

Students can use percent and per mille in the answers.

The symbol percent (%) must be typed with the keyboard while the symbol per mille (‰) has a button in the answer toolbar. If you expect the students to answer with per mille, you must provide them the MathType toolbar. Alternatively, you can provide that symbol in the question wording for them to copy & paste. They can also use the combo ALT+0137 (numeric keypad).

These symbols are similar to physical units:

  • You must use Quantity in Validation > Allowed input setting.
  • You can do basic arithmetic with them, and also convert() them.
  • You can make an algorithm with these symbols, CalcMe is going to translate it as percent and permille.
