Prefix and postfix notation

In other languages, (but apparently not in Alice) there are some unary operators that use prefix notation.

In Alice and other languages, there is at least one unary operator that uses postfix notation. 

This operator is the increment operator, which I will explain in a future lesson.

For prefix notation, the operator appears before (to the left of) its operand. 

For postfix notation, the operator appears after (to the right of) its operand.
